| 3 | A green and effective corrosion inhibitor of functionalized carbon dots显示文摘In this work, a green and effective corrosion inhibitor of functionalized carbon dots(FCDs) was synthesized by the conjugation of imidazole and citric acid carbon dots(CA-CDs). The corrosion inhibition behavior of FCDs for Q235 steel in 1 M HCl solution was systematically investigated by electrochemical analysis, corrosion morphology and adsorption isotherm. The electrochemical results implied that the as-prepared FCDs inhibitor could effectively suppress the corrosion of Q235 steel in 1 M HCl solution. At the same time, the inhibition efficiency of steel in 1 M HCl solution was more than 90% when the inhibitor concentration exceeded 100 mg/L. This excellent property was attributed to the coverage of adsorption film on the steel surface, which conformed to the Langmuir adsorption model. In addition, the analysis of adsorption isotherm displayed that the adsorption mechanism was the physicochemical interaction at the steel/solution interface. | Yuwei Ye Dongping Yang Hao Chen | 2019 | Journal of Materials Science & Technology2019，35，10： | 6 |

| 5 | Thermodynamic and Adsorption Behaviour of Medicinal Nitramine as a Corrosion Inhibitor for AISI Steel Alloy in HCl Solution显示文摘The inhibition ability of 2-amino-5-nitrothiazole(Nitramine) against the corrosion of AISI steel 4130 in 1 mol/L HCl solution was evaluated by polarization,electrochemical impedance spectroscopy(EIS) and chronoamperometry.Polarization studies indicated that nitramine retards both the cathodic and anodic reactions through chemical adsorption and blocks the active corrosion sites.The adsorption of this compound obeyed the Temkin's adsorption isotherm.The inhibition efficiency was increased with inhibitor concentration as well as temperature.EIS data were analysed by equivalent circuit model shows that as the inhibitor concentration increased the charge transfer resistance of steel increased whilst double layer capacitance decreased.Kinetic and thermodynamic parameters such as activation energy,enthalpy,entropy and free energy of activation and adsorption were calculated.Atomic force microscopy and optical microscopy were used to study the steel surface with and without inhibitor. | Ali Reza Hosein Zadeh Iman Danaee Mohamad Hosein Maddahy | 2013 | Journal of Materials Science & Technology2013，29，9： | 5 |

| 7 | Benevolent behavior of Kleinia grandiflora leaf extract as a green corrosion inhibitor for mild steel in sulfuric acid solution显示文摘The ethanolic extract of Kleinia grandiflora leaves was characterized and tested for its potential anticorrosion properties on mild steel in 1 M H2SO4 medium using mass-loss analysis, potentiodynamic polarization measurements, electrochemical impedance spectroscopy, Fourier-transform infrared spectroscopy, scanning electron microscopy, UV–visible spectroscopy, and X-ray diffraction analysis. The effect of temperature on the corrosion behavior of mild steel was studied in the range of 308 to 328 K. The inhibition efficiency was observed to increase with increasing concentration of the extract. Polarization curves revealed that the Kleinia grandiflora leaf extract is a mixed inhibitor. Impedance diagrams revealed that an increase of Kleinia grandiflora leaf extract concentration increased the charge transfer resistance and decreased the double-layer capacitance. The adsorption process obeys Langmuir's model, with a standard free energy of adsorption(ΔGads) of-18.62 k J/mol. The obtained results indicate that the Kleinia grandiflora leaf extract can serve as an effective inhibitor for the corrosion of mild steel in a sulfuric acid medium. | Muthukrishnan Pitchaipillai Karthik Raj Jeyaprabha Balasubramanian Prakash Periakaruppan | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，11： | 2 |
| 8 | Lactobionic Acid as a New Synergist in Combination with Phosphonate-Zn(Ⅱ)System for Corrosion Inhibition of Carbon Steel显示文摘Studies on lactobionic acid introduced as a synergist in the presence of phosphonobutane-1,2,4-tricarboxylic acid(PBTC) and zinc ions for corrosion control of carbon steel in aqueous environment are presented.The investigations revealed that lactobionic acid(LBA) acts as an excellent synergist in corrosion inhibition.Optimum concentrations of all the three components of the ternary formulation are established by gravimetric studies.Potentiodynamic polarization studies indicate that the new ternary system is a mixed inhibitor.Impedance studies show that a protective film is formed on the metal surface in the presence of the inhibitor formulation.The film is found to exhibit its protective nature even at higher temperatures up to 60 °C.Analysis of the protective film by X-ray photoelectron spectroscopy(XPS) and reflection absorption Fourier transform infrared(FTIR) spectroscopy infers the presence of Zn(OH)_2,oxides and hydroxides of iron and the inhibitor molecules in the surface film probably in the form of a complex,[Zn(ll)—PBTC—LBA].The morphological studies by scanning electron microscopy(SEM) and the topographical studies by atomic force microscopy(AFM) also indicate the presence of protective film on the metal surface.A plausible mechanism of corrosion inhibition is proposed. | S.Srinivasa Rao B.V.Appa Rao S.Roopas Kiran B.Sreedhar | 2014 | Journal of Materials Science & Technology2014，30，1： | 2 |
| 9 | 地面管网含硫酸性腐蚀环境用缓蚀剂的性能与作用机制显示文摘为了改善地面管网含硫酸性高温环境的腐蚀问题,用微波法合成了一种N掺杂碳点缓蚀剂NCDs,采用电化学和失重法测试了NCDs在25、60、90℃下对N80钢片在模拟溶液中的缓蚀作用。结果表明,在相同NCDs浓度下,随温度的升高,缓蚀效率降低。在25℃下,缓蚀剂NCDs质量浓度为150 mg/L时的缓蚀效率达到最大,达94.16%;在60℃下,NCDs质量浓度为200 mg/L时的缓蚀效率最大,为82.92%;在90℃下,NCDs质量浓度为150 mg/L时缓蚀效率达到69.59%。对腐蚀形貌分析发现90℃时,钢片表面的腐蚀坑深度和数目最多。吸附等温曲线表明,NCDs在90℃时吸附平衡常数最大,但高温会使其局部腐蚀更严重。此外发现N掺杂碳点的吸附类型为物理与化学混合吸附。该碳点缓蚀剂可有效解决地面管道高温下的腐蚀,延长使用寿命。 | 李薛 孙振华 周海刚 魏旭 周兆院 刘晶姝 | 2023 | 油田化学2023，40，3： | 0 |
| 10 | Combined Computational and Experimental Study on the Adsorption and Inhibition Effects of N_2O_2 Schiff Base on the Corrosion of API 5L Grade B Steel in 1 mol/L HCl显示文摘The electrochemical behavior of low carbon steel(API 5L grade B) in 1 mol/L HCl solution with different concentrations of N,N0-bis(4-formylphenol)-trimethylenediamine Schiff base was studied by electrochemical techniques and density functional theory analysis. The inhibition efficiency was found to increase with increasing inhibitor concentration and decreased with increasing temperature. The high inhibition efficiency was attributed to the blocking of active sites by adsorption of inhibitor molecules on the steel surface.Thermodynamic parameters for the adsorption and activation processes were determined. Galvanostatic polarization data indicated that Schiff base act as a mixed-type inhibitor and the adsorption isotherm obeyed the Langmuir adsorption isotherm. Results obtained from quantum chemical studies show excellent correlations between the quantum chemical parameters and the experimental inhibition efficiencies using density functional theory at the B3LYP/6-31G(d,p) and B3LYP/3-21G basis set levels and ab initio calculations using HF/6-31G(d,p) and HF/3-21G methods. | Hojat Jafari Iman Danaee Hadi Eskandari Mehdi RashvandAvei | 2014 | Journal of Materials Science & Technology2014，30，3： | 0 |
