| 1 | Microstructural Evolution and Mechanical Properties of Inconel 625 Alloy during Pulsed Plasma Arc Deposition Process显示文摘Pulsed plasma arc deposition(PPAD),which combines pulsed plasma cladding with rapid prototyping,is a promising technology for manufacturing near net shape components due to its superiority in cost and convenience of processing.In the present research,PPAD was successfully used to fabricate the Ni-based superalloy Inconel 625 components.The microstructures and mechanical properties of deposits were investigated by scanning electron microscopy(SEM),optical microscopy(OM),transmission electron microscopy(TEM) with energy dispersive spectrometer(EDS),microhardness and tensile testers.It was found that the as-deposited structure exhibited homogenous columnar dendrite structure,which grew epitaxially along the deposition direction.Moreover,some intermetallic phases such as Laves phase,minor MC(NbC, TiC) carbides and needle-likeδ-Ni_3Nb were observed in y-Ni matrix.Precipitation mechanism and distribution characteristics of these intermetallic phases in the as-deposited 625 alloy sample were analyzed.In order to evaluate the mechanical properties of the deposits,microhardness was measured at various location (including transverse plane and longitudinal plane).The results revealed hardness was in the range of 260—285 HV_(0.2).In particular,microhardness at the interface region between two adjacent deposited layers was slightly higher than that at other regions due to highly refined structure and the disperse distribution of Laves particles.Finally,the influence of precipitation phases and fabrication strategies on the tensile properties of the as-deposited samples was investigated.The failure modes of the tensile specimens were analyzed with fractography. | Fujia Xu Yaohui Lv Yuxin Liu Fengyuan Shu Peng He Binshi Xu | 2013 | Journal of Materials Science & Technology2013，29，5： | 33 |
| 2 | Study on magnetic memory signals of medium carbon steel specimens with surface crack precut during loading process显示文摘Static tensile test and tensile-tensile fatigue test of medium carbon steel sheet specimens with surface crack precut were performed on MTS810 hydraulic testing machine to clear the meaning of the point of Hp(y) value zero. Magnetic memory signals were measured during the test process. The results show that only one point of Hp(y) zero value exists in all measured magnetic signal curves during the loading process, which should be a sign of intersection of positive-negative magnetic poles after magnetic ordered state appears and does not indicate the position of surface crack precut. The analysis shows that the surface crack precut can not interrupt the magnetic ordered state occurred during the test completely, hence its Hp(y) value is not zero. However, the crack extending to a penetrated defect at the instant of specimen′s fracture leads to the discontinuance of magnetic ordered state. | DONG Lihong XU Binshi DONG Shiyun YE Minghui CHEN Qunzhi | 2006 | Rare Metals2006，25，z1： | 9 |
| 3 | Preparation of Al-based Amorphous/Nanocrystalline Composite Coating on Mg-based Alloys Precipitated by Arc Spraying Process显示文摘The Al-based amorphous and nanocrystalline composite coatings with the composition of Al-Ni-Y-Co and Al-Ni-Mm-Fe were prepared on AZ91 Mg-based alloys by high velocity arc spraying technique(HVAS).The structure character of the coatings indicates that coatings contain the mixture of amorphous phases and crystalline and there are both less than 2%porosity.The electrochemical tests of the coatings and the substrate were studied.The coatings show the passivation ability during polarization,but AZ91 Mg-based alloys show little passivation.The corrosion current density of the coatings is lower than that of AZ91 Mg-based alloys.The results show that the coatings have an excellent corrosion resistance for AZ91 Mg-based alloys in 5 wt%NaCl solution. | Zhang Zhibin Liang Xiubing Xu Binshi | 2012 | 稀有金属材料与工程2012，41，S1： | 4 |
| 4 | The Erosion Effect of Kapton Film in a Ground-based Atomic Oxygen Irradiation Simulator显示文摘In order to investigate the effect of space environmental factors on spacecraft materials, a ground-based simulation facility for space atomic oxygen(AO) irradiation was developed in our laboratory. Some Kapton film samples were subjected to AO beam generated by this facility. The Kapton films before and after AO exposure were analyzed comparatively using optical microscopy, scanning electronic microscopy, atomic force microscopy, high-precision microbalance, and X-ray photoelectron spectroscopy. The experimental results indicate that the transmittance of Kapton film will be reduced by AO irradiation notably, and its color deepens from pale yellow to brown. Surface roughness of the AO-treated sample is already increased obviously after AO irradiation for 5 hours, and exhibits a flannel-like appearance after 15 hours' exposure in AO beam. The imide rings and benzene rings in kapton molecule are partially decomposed, and some new bonds form during AO irradiation. The mass loss of kapton film increases linearly with the increase of AO fluence, which is resulted from the formation of volatile products, such as CO, CO2 and NOx. The breakage in structure and degradation in properties of AO-treated Kapton film can be attributed to the integrated effect ofimpaction and oxidization of AO beam. The test results agree well with the space flight experimental data. | 王海斗 MA Guozheng XU Binshi XING Zhiguo LI Guolu ZHANG Sen | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，6： | 4 |
| 5 | High Velocity Electric Arc Sprayed Fe-Al-Nb-B Composite Coating and Its Wear Behavior显示文摘A type of Fe-Al-Nb-B cored wire was designed and the coating was prepared using a robot-based electric wire arc spraying process. The Fe-Al binary cored wire and coating were also prepared as comparison. The phase composition and structure of the coatings were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The coating tribological properties were evaluated with the micromotion wear tester under different conditions. The results show that, although typical lamellar structure was performed for both the arc sprayed Fe-Al-Nb-B coating and Fe-Al coating, the structure composition, mechanical and wear properties of the former are quite different from those of latter. The Fe-Al-Nb-B coating is a typical composite coating, which is distributed inhomogeneously with α-Fe crystalline, FeAl and Fe 3 Al intermetallics, amorphous and nanocrystallines as well as locally existed oxide phases. As a result, the mircrohardness and wear resistance of the Fe-Al-Nb-B composite coating increased significantly. Finally the mechanism of the coating wear resistant behavior was discussed based on the experimental results such as friction coefficient, two dimensional and three dimensional worn surface profiles. | Yongxiong CHEN Xiubing LIANG Jinyuan BAI Binshi XU | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，3： | 4 |

| 7 | Vacuum carburization of 12Cr2Ni4A low carbon alloy steel with lanthanum and cerium ion implantation显示文摘As bearing parts, 12 Cr2 Ni4 A is expected to have high hardness and excellent fatigue strength, so carburizing is employed to improve the inherit properties of 12 Cr2 Ni4 A. However, the traditional carburizing is limited by poor microstructure distribution and low rate of carburizing. The rare earth ion implantation is known to help improving the properties of tribology, corrosion resistance and oxidation resistance of metal. In this article, the RE implantation is employed to assist the carburizing. Lanthanum and cerium ion implantations are initially used to assist 12 Cr2 Ni4 A low pressure vacuum carburization.The microstructure, content of retained austenite, hardness, thickness of layer and carbon diffusion were analyzed by optical microscopy(OM), scanning electron microscopy(SEM), X-ray diffraction(XRD) and Rockwell/Vickers hardness tester, respectively. It was shown that lanthanum and cerium implantations can improve structure of the vacuum carburizing layer, and enhance the uniformity of carbon element distribution on the carburized surface. Meanwhile the RE implantation plays a positive role in promoting the surface hardness and carburized rate. The lanthanum element has more significant effect on surface hardness and content of retained austenite than cerium element. The surface hardness of lanthanum element implanted layer was 62.9 HRC with 9.6% content of retained austenite, while the carburizing rate of cerium implanted layer increased by 12.4%. | Meiling Dong Xiufang Cui Yuhui Zhang Guo Jin Caiwen Yue Xin Zhao Zhaobing Cai Binshi Xu | 2017 | Journal of Rare Earths2017，35，11： | 3 |
| 8 | Effect of electromagnetic stirring on the microstructure and wear behavior of iron-based composite coatings显示文摘The effect of electromagnetic stirring on the microstructure and wear behavior of coatings has been investigated. A series of iron-based coatings were fabricated by the plasma-transferred arc cladding process by applying different magnetic field currents. The microstructure and wear resistance of the composite coatings were characterized by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDAX), X-ray diffraction (XRD), and wet sand rubber wheel abrasion tester. The experimental re- sults showed that the microstructure of the coatings was mainly the γ-Fe matrix and (Cr, Fe)7C3 carbide reinforced phase. The coatings were metallurgically bonded to the substrate. With increasing magnetic field current, the amount of the block-like (Cr, Fe)7C3 carbide reinforced phase increased at first, reached a local maximum, and then decreased sharply. When the magnetic field current reached 3 A, the block-like (Cr, Fe)7C3 carbides with high volume fraction were uniformly distributed in the matrix and the coating displayed a high microhardness and an excellent wear resistance under the wear test condition. | Jiangbo Cheng Binshi Xu Xiubing Liang Yixiong Wu Zhengjun Liu | 2008 | Journal of University of Science and Technology Beijing2008，15，4： | 3 |
| 9 | Microstructure and Tribological Properties of PlasmaSprayed Ni/MoS_2 Solid Lubrication Coating显示文摘A composite Ni based MoS2 solid lubrication coating was prepared using the plasma spraying technology with optimized process parameters.The tribological properties of the composite Ni/MoS2 coatings in air and vacuum were studied with a ball-on-disk friction and wear tester under dry sliding condition,respectively.XRD,SEM and EDS were adopted to analyze the microstructures of the coating before and after wear tests.Results showed that the deposition quality of the coating was good.The content of lubricant MoS2 was high.But the compactability of the coating with many superficial micrometersized defects such as pores and cracks was relatively low.The composite Ni/MoS2 coating exhibited excellent friction-reduction properties both in air and in vacuum conditions.In vacuum,the wear loss was greater because the severe spalling of top layer resulted from breakthrough of the adjacent defects.In air condition,the wear loss of the coating was relatively low but its friction-reduction ability may be weakened for the oxidation of MoS2. | Ma Guozheng,Xu Binshi,Wang Haidou,Yang Daxiang National Key Laboratory for Remanufacturing,Academy of Armored Forces Engineering,Beijing 100072,China | 2012 | 稀有金属材料与工程2012，41，S1： | 3 |
