一、前言由于钛具有优良的耐蚀性,作为各种化学装置的结构材料被广泛应用。但是在高温氯化物等溶液中往往发生缝隙腐蚀,为此人们期望研究出一种简便的防止方法。本实验,以提高钛的耐缝隙腐蚀性能为目的,对于用 PdO 和 RuO_2—TiO_2混合氧化物进行表面处理的钛材,在探讨了抗缝隙腐蚀性能与表面处理条件的关系的同时,对表面膜的结构也进行了分析。
I. INTRODUCTION Since titanium has excellent corrosion resistance, it is widely used as a structural material of various chemical devices. However, crevice corrosion often occurs in solutions such as high temperature chlorides, for which reason one expects to find a convenient method of prevention. In this experiment, to improve the crevice corrosion resistance of titanium for the purpose of the PdO and RuO_2-TiO_2 mixed oxide surface treatment of titanium, the relationship between anti-crevice corrosion resistance and surface treatment conditions at the same time, the surface film The structure is also analyzed.
