| 1 | Anaerobic microbiologically influenced corrosion mechanisms interpreted using bioenergetics and bioelectrochemistry: A review显示文摘Microbiologically influenced corrosion(MIC) is a major cause of corrosion damages, facility failures, and financial losses, making MIC an important research topic. Due to complex microbiological activities and a lack of deep understanding of the interactions between biofilms and metal surfaces, MIC occurrences and mechanisms are difficult to predict and interpret. Many theories and mechanisms have been proposed to explain MIC. In this review, the mechanisms of MIC are discussed using bioenergetics, microbial respiration types, and biofilm extracellular electron transfer(EET). Two main MIC types, namely EET-MIC and metabolite MIC(M-MIC), are discussed. This brief review provides a state of the art insight into MIC mechanisms and it helps the diagnosis and prediction of occurrences of MIC under anaerobic conditions in the oil and gas industry. | Yingchao Li Dake Xu Changfeng Chen Xiaogang Li Ru Jia Dawei Zhang Wolfgang Sand Fuhui Wang Tingyue Cu | 2018 | Journal of Materials Science & Technology2018，34，10： | 43 |

| 3 | Electrochemical Corrosion Behavior of Nanocrystalline Materials-a Review显示文摘Nanocrystallization significantly infiuences the electrochemical corrosion behaviors of metals/alloys in liquid system. In active dissolution, nanocrystallization accelerates the corrosion reactions. If the corrosion products are dissoluble, the corrosion rate is increased by nanocrystallization; if the corrosion products are insoluble, the corrosion rate is decreased on the contrary because the corrosion products act as a block layer to delay the dissolution. In passivation, nanocrystallization changes the composition of the passive film, and results into different morphology and growth process of the passive film, both of which improves the formation of compact film and influences the semiconductor property. It influences the passivation depending on fast element diffusion and special adsorbed ability. The small grain size improves the element diffusion, which leads to the different composition of passive film (passive elements enrichment such as Cr, Ti). The small grain size also changes the surface condition, which influences the ions adsorption. All increase the corrosion resistance of materials. In local corrosion, nanocrystallization increases the unstable points on the surface of the materials, which increases the possibility of local corrosion. However, the excellent ability of element diffusion helps heal the local corrosion points, which inhibits the growth of the local corrosion. | Li Liu, Ying Li and Fuhui Wang State Key Laboratory for Corrosion and Protection, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China | 2010 | Journal of Materials Science & Technology2010，26，1： | 12 |
| 4 | Electrochemical corrosion behavior of 2A02 Al alloy under an accelerated simulation marine atmospheric environment显示文摘The corrosion behavior of 2 A02 Al alloy under simulated marine atmospheric environment has been studied using mass-gain, scanning electron microscope/energy dispersive spectroscopy(SEM/EDS), laser scanning confocal microscopy, X-ray diffraction spectroscopy and localized electrochemical methods. The results demonstrate that the relationship between the corrosion induced mass-gain and the corrosion time is in accordance with the power rule. The mass-gain increases gradually during the corrosion time,while the corrosion rate decreases. With ongoing of the corrosion, corrosion products film changed from a porous to a compact structure. The various spectroscopic data show that the corrosion products films composed mainly of Al(OH)_3, Al_2O_3 and AlCl_3. The electrochemical corrosion behavior of the 2 A02 Al alloy was studied by electrochemical impedance spectroscopy(EIS). | Min Cao Li Liu Zhongfen Yu Lei Fan Ying Li Fuhui Wang | 2019 | Journal of Materials Science & Technology2019，35，4： | 11 |
| 5 | Effect of Cl^- on the Properties of the Passive Films Formed on 316L Stainless Steel in Acidic Solution显示文摘The corrosion behavior of 316L stainless steel(316L SS) has been investigated in solutions containing various concentrations of chloride ions by using potentiodynamic polarization, capacitance measurement and Motte Schottky relationship analysis(Me S). The result indicates that passive currents change slightly with the addition of chloride ions. The pitting potential(Epit) decreases linearly with log[Cl ]. Correspondingly, the point defect diffusion coefficient(Do) of the passive film increases linearly with increasing log[Cl ]. The results also indicate that the pitting corrosion of 316L SS follows the adsorption mechanism in NaCl solution. | Guozhe Meng Yuan Li Yawei Shao Tao Zhang Yanqiu Wang Fuhui Wang | 2014 | Journal of Materials Science & Technology2014，30，3： | 10 |
| 6 | Wind speed prediction by chaotic operator network based on Kalman Filter显示文摘A novel prediction network composed of some chaotic operators is proposed to predict the wind speed series.Training samples are constructed by the theory of phase space reconstruction.Genetic algorithm is adopted to optimize the control parameters of chaotic operators to change the dynamic characteristic of the network to approach to the predicted system.In this way,the dynamic prediction of wind speed series can be completed.The wind acceleration series can also be predicted by the same network.And the prediction results of both series can be fused by Kalman Filter to get the optimal estimation prediction result of the wind speed series,which is superior to the result obtained by each single method.Simulation results show that the prediction network has less computation cost than BP neural network,and it has better prediction performance than BP neural network and autoregressive integrated moving average model.Kalman Filter can improve the prediction performance further. | XIU ChunBo GUO FuHui | 2013 | Science China(Technological Sciences)2013，56，5： | 9 |
| 7 | Influence of Sputtered Nanocrystalline Coating on Oxidation and Hot Corrosion of a Nickel-based Superalloy M951显示文摘The isothermal and cyclic oxidation behaviors in air and hot corrosion behaviors in Na2SO4t 25 wt%K2SO4salt of M951 cast superalloy and a sputtered nanocrystalline coating of the same material were studied.Scanning electron microscopy,energy dispersive X-ray spectroscope,X-ray diffraction,and transmission electron microscopy were employed to examine the morphologies and phase composition of the M951 alloy and nanocrystalline coating before and after oxidation and hot corrosion.The as-sputtered nanocrystalline layer has a homogeneous g phase structure of very fine grain size(30e200 nm)with the preferential growth texture of(111)parallel to the interface.Adherent Al2O3rich oxide scale formed on the cast M951 alloy and its sputtered coating after isothermal oxidation at 900 and 1000 C.However,when being isothermal oxidized at 1100 C and cyclic oxidized at 1000 C,the oxide scale formed on the cast alloy was a mixture of NiO,NiAl2O4,Al2O3and Nb2O5and spalled seriously,while that formed on the sputtered coating mainly consisted of Al2O3and was very adherent.Nanocrystallization promoted rapid formation of Al2O3scale during the early stage of oxidation and enhanced the adhesion of the oxide scale,thus improved the oxidation resistance of the substrate alloy.Serious corrosion occurred for the cast alloy.The sputtered nanocrystalline coating apparently improved the hot corrosion resistance of the cast alloy in the mixed sulfate by the formation of a continuous Al2O3and Cr2O3mixed oxide layer on the surface of the coating,and the preoxidation treatment of the coating led to an even better effect. | Xinyue Wang Li Xin Fuhui Wang Shenglong Zhu Hua Wei Xiaolan Wang | 2014 | Journal of Materials Science & Technology2014，30，9： | 9 |
| 8 | Multifunctional superhydrophobic coatings fabricated from basalt scales on a fluorocarbon coating base显示文摘Superhydrophobic coatings are increasingly being evaluated as anticorrosion interventions in exceedingly hydrated environments.However,concerns about their long-term durability and amenability to large-area applications in marine environments are still hindering commercial-scale deployment.This study is focused on development of easy-to-apply superhydrophobic coatings,with multifunctional capabilities,in order to extend the integrity and durability of the coatings in harsh marine environments.Here,a set of facile methods involving selective chemical etching using concentrated Na OH,as well as fluorination with perfluoropolyether methyl ester were adopted to fabricate a superhydrophobic surface on basalt scales,having the required rough hierarchical micro-nanotextured and low surface energy.The superhydrophobic basalt scales were subsequently aligned atop a fluorocarbon resin,pre-deposited on a metal substrate,to yield a multifunctional superhydrophobic coating(3μL water droplet;contact angle=165.1°,rolling angle=0.7°),easily amenable to large surface area application and having excellent wear resistance,UV-aging resistance,salt spray resistance,corrosion resistance and antibacterial capabilities. | Hongpeng Zheng Li Liu Fandi Meng Yu Cui Zhong Li Emeka E.Oguzie Fuhui Wang | 2021 | Journal of Materials Science & Technology2021，，25： | 8 |
| 9 | Significantly improved corrosion resistance of Mg-15Gd-2Zn-0.39Zr alloys: Effect of heat-treatment显示文摘The effects of heat-treatment on corrosion behavior of Mg-15Gd-2Zn-0.39Zr alloys were investigated through microstructure characterization, corrosion tests, and scanning Kelvin probe force microscope(SKPFM) analysis. In long-term corrosion experiments, the corrosion rates of Mg-Gd-Zn-Zr alloys were mainly determined by the effects of micro-galvanic corrosion. During heat-treatment, the β-(Mg,Zn)3Gd eutectic phase in as-cast alloys transformed into a long-period stacking ordered(LPSO) phase, coupled with the precipitation of small precipitates. As heat-treatment proceeded, the local potential and the volume fraction of the LPSO phases reduced gradually compared with the eutectic phase, which resulted in a remarkable decrease of the micro-galvanic effect between the second phase and Mg matrix. As a result, the corrosion resistance of heat-treated alloys improved significantly. | Jing Liu Lixin Yang Chunyan Zhang Bo Zhang Tao Zhang Yang Li Kaiming Wu Fuhui Wang | 2019 | Journal of Materials Science & Technology2019，35，8： | 8 |

| 11 | Microstructure and composition evolution of a single-crystal superalloy caused by elements interdiffusion with an overlay NiCrAlY coating on oxidation显示文摘MCrAlY(M=Ni and/or Co)overlay coating is widely used as a protective coating against high temperature oxidation and corrosion.However,due to its big difference in chemical composition with the underlying superalloy,elements interdiffusion occurs inevitably.One of the direct results is the formation of interdiffusion zone(IDZ)and secondary reaction zone(SRZ)with a high density of fine topological closed-packed phases(TCPs),weakening dramatically the mechanical properties of the alloy substrate.It is by now the main problem of modern high-temperature metallic coatings,but there are still hardly any reports studying the formation,growth and transformation of IDZ and SRZ in deep,as well as the precipitation of TCPs.In this work,a typical NiCrAlY coating is deposited by arc ion plating on a single-crystal superalloy N5.Elements interdiffusion between them and its relationship on microstructure were clarified.Cr rather than Al from the coating diffuses into the alloy at high temperatures and segregates immediately beneath their interface,contributing largely to the formation of IDZ.Simultaneously,diffusion of Ni from the deep alloy to IDZ leads to the formation and continuous expansion of SRZ. | Lanlan Yang Minghui Chen Jinlong Wang Yanxin Qiao Pingyi Guo Shenglong Zhu Fuhui Wang | 2020 | Journal of Materials Science & Technology2020，42，10： | 7 |
| 12 | A novel Cu-bearing high-entropy alloy with significant antibacterial behavior against corrosive marine biofilms显示文摘The design of novel high-entropy alloys(HEAs)provides a unique opportunity for the development of structure-function integrated materials with high mechanical and antimicrobial properties.In this study,by employing the antibacterial effect of copper,a novel Al0.4CoCrCuFeNi HEA with broad-spectrum antibacterial and strong mechanical properties was designed.High concentrations of copper ions released from the HEA prevented growth and biofilm formation by biocorrosive marine bacterial species.These findings serve as a proof-of-concept for further development of unique HEA materials with high antimicrobial efficiency and mechanical properties,compared to conventional antibacterial alloys. | Enze Zhou Dongxu Qiao Yi Yang Dake Xu Yiping Lu Jianjun Wang Jessica A.Smith Huabing Li Hongliang Zhao Peter K.Liaw Fuhui Wang | 2020 | Journal of Materials Science & Technology2020，42，11： | 6 |
| 13 | STOCHASTIC CRACKING AND HEALING BEHAVIORS OF THIN FILMS DURING REACTION-DIFFUSION GROWTH显示文摘The stochastic cracking and healing behaviors of reaction-diffusion growth of thin films were studied by means of Markov processes analysis. We chose the thermal growth of oxide scales on metals as an example of reaction-diffusion growth. The thermal growth of oxide films follows power law when no cracking occurs. Our results showed that the growth kinetics under stochastic cracking and healing conditions was different from that without cracking. It might be altered to either pseudo-linear or pseudo-power laws dependent upon the intensity and frequency of the cracking of the films. When the hoping items dominated, the growth followed pseudo-linear law; when the diffusional items dominated, it followed pseudo-power law with the exponentials lower than the intrinsical values. The numerical results were in good agreement with the meassured kinetics of isothermal and cyclic oxidation of NiAl-0.1 Y (at. %) alloys in air at 1273K. | S.L. Zhu, S.L. Yang, Y.M. Xiong, M.S.

| 15 | Methanogenic archaea and sulfate reducing bacteria induce severe corrosion of steel pipelines after hydrostatic testing显示文摘Complex interactions within a microbial consortium can induce severe corrosion in oil pipelines.This study investigated the mechanism of microbiologically influenced corrosion(MIC)that led to failure of X52 steel pipelines after hydrostatic testing.Laboratory hydrostatic testing with untreated lake water and underground water were used to simulate and study the events that led to the actual corrosion.Biofilm analysis,weight loss,and several electrochemical measurements demonstrated rapid corrosion rates after hydrostatic testing.Analysis of microbial community structures revealed that methanogenic archaea and sulfate reducing bacteria(SRB),introduced by the hydrotest water,formed corrosive biofilms on X52 steel coupon surfaces that induced severe pitting. | Enze Zhou Jianjun Wang Masoumeh Moradi Huabing Li Dake Xu Yuntian Lou Jinheng Luo Lifeng Li Yulei Wang Zhenguo Yang Fuhui Wang Jessica A.Smith | 2020 | Journal of Materials Science & Technology2020，47，13： | 5 |
| 16 | Finite element analysis of effect of interfacial bubbles on performance of epoxy coatings under alternating hydrostatic pressure显示文摘The stresses around bubbles formed on a coating/substrate interface under hydrostatic pressure(HP)and alternating hydrostatic pressure(AHP)were calculated using the finite element method.The results reveal that HP promotes coating failure but does not mechanically destroy the interface,whereas AHP can provide tensile stress on bubbles formed at the interface and accelerate disbonding of the coating.Because of water resistance,a lag time exists for the coating that serves in an AHP environment.The coating can have a better protective performance if the lag time suits the AHP to minimize the impact of the AHP on the interface. | Rui Liu Li Liu Wenliang Tian Yu Cui Fuhui Wang | 2021 | Journal of Materials Science & Technology2021，，5： | 5 |
| 17 | Effect of Microstructures on Corrosion Behavior of Nickel Coatings:(Ⅱ) Competitive Effect of Grain Size and Twins Density on Corrosion Behavior显示文摘Nanocrystalline nickel coatings with grain size of 50 nm were annealed in vacuum at 200°C and 400°C for 10 min.Their microstructures were investigated by transmission electron microscopy(TEM).And their corrosion behaviors were studied by means of polarization and electrochemical impedance spectroscopy(EIS).The results showed that their grain size grew up to about 60 nm(200°C)and 500 nm(400°C),respectively.The specimen annealed at 200°C possessed higher density of twins in compared with the counterparts of as-deposited and annealed at 400°C.The normal grain size effect on the corrosion behavior was not observed.However,it was found that the corrosion resistance of the coating linearly changed with the density of twins. | Guozhe Meng Yang Li Yawei Shao Tao Zhang Yanqiu Wang Fuhui Wang Xuequn Cheng Chaofang Dong Xiaogang Li | 2016 | Journal of Materials Science & Technology2016，32，5： | 5 |
| 18 | Role of Al_(18)B_4O_(33) Whisker in MAO Process of Mg Matrix Composite and Protective Properties of the Oxidation Coating显示文摘Selective growth of oxidation coating was observed on Mg matrix composite Al18B4O33w/AZ91(a composite with Al18B4O33 crystal whisker as reinforced phase) when this composite was treated by microarc oxidation (MAO) technique,and then the role of Al18B4O33 whisker in the process of MAO was analyzed.The protective properties of MAO coating also were investigated.Scanning electron microscopy(SEM) was used to characterize the existing state of Al18B4O33 whisker in MAO process and the microstructure of MAO coating.Corrosion resistance of the bare and coated composite was evaluated by immersion corrosion test and potentiodynamic polarizing test.Wear resistance of MAO coating was investigated by a ball-on-disc friction and wear tester.The results showed that sparking discharge did not occur on Al18B4O33 whisker and the whisker existed in the coating as a heterogeneous phase when MAO coating grew on the composite;then the whisker would be covered gradually with growing thick of the coating.Corrosion current density of the coated composite was decreased by 4 orders of magnitude compared with that of the uncoated composite; excellent corrosion resistance was closely related to the compact whisker-coating interface since Al18B4O33 whisker did not induce structural defects.The coating also exhibited high wear resistance and a slight adhesive wear tendency with bearing steel as its counterpart material. | Yanqiu Wang Xiaojun Wang Kun Wu Fuhui Wang | 2013 | Journal of Materials Science & Technology2013，29，3： | 5 |

In this study, several titanium aluminum nitride films were deposited on 1Cr11Ni2W2MoV steel for compressor blade of areo-engine under different d.c pulse bias voltage and nitrogen partial pressure. The effects of substrate pulse bias and nitrogen partial pressure on the deposition rate, droplet formation, microstruture and elemental component of the films were investigated. | M.S. Li, S.L.

| 20 | Oxidation and Thermal Shock Behavior of a Glass-Alumina Composite Coating on K38G Superalloy at 1000℃显示文摘The glass-alumina composite coatings were successfully prepared on the K38G superalloy substrates.Their isothermal oxidation and thermal shock behavior at 1000 ℃ were characterized.With a post-annealing process at 850 ℃,the composite coatings possessed an improved protective effect for the alloy substrates from isothermal oxidation and a higher resistance to thermal shock.Crystallization from the glass matrix and interfacial reaction between the matrix and alumina inclusions,which caused the composites more refractory and tough,accounted for this improvement.The micromechanisms for the formation of oxidation results of spinel ZnCr_2O_4 were also discussed. | Minghui Chen Mingli Shen Xin Wang Shenglong Zhu Fuhui Wang | 2012 | Journal of Materials Science & Technology2012，28，5： | 4 |
