不锈钢的表面着色制备

Preparing Color Stainless Steel

对碱性着色法、硫化法和酸性着色法进行了实验操作和反应条件的探讨。对酸性着色法的配方和工艺条件进行了优化改进 ,结果获得了耐磨性好 ,光泽佳的 7种着色不锈钢。进一步实验研究了微量添加剂对着色的影响。结果发现微量添加剂可使着色速度加快 ,色彩鲜艳。

Stainless steel is a beautiful material.It is widely used in industry and in daily life as a decorative material.There are a lot of reports and patents of making color stainless steel.But it is too expensive to be used generally.A Cheaper making method is demanded.Seven methods have bee tested in our laboratory.We found that acidic coloring method is better than others.Some improvements have been done in acidic coloring method and optimum conditions are found in our experimental search.
