讨论了 3Cr13不锈钢在含有添加剂的低浓度铬酐 硫酸溶液中 ,进行化学着色处理的工艺和各种添加剂对表面着色的影响。结果表明 :铬酐含量可降至 60～ 80g/L ,并根据着色时间的不同获得多种色彩的着色外观。着色膜层耐候性、耐磨性优良。
The effects of chemical coloring treatment and various additives on surface coloration of 3Cr13 stainless steel in low concentration chromic anhydride sulfuric acid solution containing additives were discussed. The results showed that the content of chromic anhydride could be reduced to 60 ~ 80g / L, and a variety of colored appearances were obtained according to the coloring time. Coloring film weathering, wear resistance.
