利用电化学方法对金属表面进行修饰是近期发展的一种有效的防腐蚀手段。论文工作主要研究了苯胺及其衍生物(联苯胺、邻甲苯胺和对甲苯胺)在铁基金属的表面的电化学修饰。对其修饰工艺条件进行了探索,采用极化电阻、稳态极化曲线、交流阻抗等电化学测试技术检测了修饰试样在不同介质中的耐蚀性能,用多种现代物理表面分析技 The use of electrochemical methods to modify the metal surface is an effective anti-corrosion method developed recently. Thesis work mainly studies the electrochemical modification of aniline and its derivatives (benzidine, o-toluidine and p-toluidine) on the surface of iron-based metals. The modified process conditions were explored. The corrosion resistance of the modified samples was tested in different media by using the polarization resistance, steady-state polarization curve and AC impedance electrochemical testing techniques. With a variety of modern physical surface analysis techniques
