摘要/Abstract

摘要： 研究了不同Ｃｒ含量的Ｆｅ＿Ｃｒ合金在Ｈ２ＳＯ４溶液体系中的摩擦腐蚀过程．重点考察了载荷、摩擦速度、Ｃｒ含量及Ｈ２ＳＯ４溶液浓度对摩擦电流密度的影响．结果表明：当摩擦仅作用在金属部分表面时，在钝化电位区，外加载荷和摩擦速度对摩擦电流密度有较大的影响．合金材料耐蚀性的增加或溶液腐蚀性的降低，都将有利于降低Ｆｅ＿Ｃｒ合金材料在Ｈ２ＳＯ４溶液体系中的流失速度

Abstract: The tribocorrosion process of Fe_Cr alloys with different Cr content in H2SO4 solution was investigated.The influence of applied load, friction velocity, Cr content and concentration of H2SO4 in solution on the triboelectrochemical behaviors of the alloys was analyzed. It is shown that applied load and friction velocity have singnificant influence on the tribocurrent density in passive region when friction process occurs on part of the surface of alloy.Increasing the corrosion resistance of alloys or decreasing the aggressive of the solution can reduce the alloy removal velocity.

Key words: Passivity, Metallic material, Triboelectrochemistry
