彩色不锈钢生产工艺及其耐蚀性的研究

Colouring Process of Stainless Steel and Corrosion Resistance of the Film

采用添加了ＣＳ－１添加剂的常规的不锈钢着色液可以生产出彩色不锈钢。所获彩色膜除包括在常规的着色液中可获得的颜色外，还能着出茶色、咖啡色、古铜色等颜色。通过动电位扫描极化曲线等的测量和分析，研究了所得着色膜的耐蚀性能，并解释着色膜经硬化处理后，耐蚀性得到提高的原因。

Coloured stainless steel can be produced by treating stainless steel in a conventional colouring solution containing Additive CS-1. The obtainable film colours may be dark brown, coffee and bronze besides the colours generally obtainable from conventional colouring solutions. Corrosion resistance of the films obtained was investigated through determination and analysis of the potentiodynamic polarization curves. The reasons why corrosion resistance of the coloured film can be improved by hardening process were elucidated.
