本文用XPS研究了SUS36不锈钢在添加Na_2MoO_4缓蚀剂的醛化液中,在不同阳极极化电位下形成的表面膜的组份及其深度分布。表明在阳极过钝化电位下形成的钝化膜在醛化液中具有较好的耐蚀性。
Passive films on SUS36 stainless steel formed in vinylon formalin condensation with. Na_2MoO_4 and polarized under various potentials have been studied with the aid of X-ray photoelcctron spectra. It has been found that the corrosion resistance of passive film formed in anodic transpassive potential region (1020mV) is, much better than those formed in other anodic passive potentials (<950mV).
