一、前言不锈钢(1Cr18Ni9Ti)在H_2SO_4-CrO_3和H_2SO_4-NH_4·VO_3体系中染色后,获得染色膜的组织是疏松多孔的,和铝在H_2SO_4溶液中阳极氧化膜的组织相似。另外,染色膜很薄(仅有10~3A数量级)。所以,未经硬化处理的染色膜其耐磨性和耐污性均不佳,也就没有使用价值。为了增加这种膜的耐磨性和耐污性,现在都采用硬化处理。关于硬化处理,国外资料介绍了三种方法:高温氧化处理硬化法;涂料法;电解硬
I. INTRODUCTION The structure of the dyed film obtained after dyeing stainless steel (1Cr18Ni9Ti) in H_2SO_4-CrO_3 and H_2SO_4-NH_4 · VO_3 system is porous and porous, similar to that of aluminum in H_2SO_4 solution. In addition, the dyed film is very thin (only on the order of 10 to 3A). Therefore, the non-hardened dyed film of its wear resistance and stain resistance are poor, there is no value. In order to increase the wear resistance and stain resistance of the film, hardening treatment is now used. About hardening treatment, foreign materials introduced three methods: high temperature oxidation hardening method; coating method; electrolytic hard
