Study on Coloration of Zinc Plated Steel Materials by Metal Surface Treatment.

Abstract

We examined methods to give chromatic color or achromatic color to zink plated steel materials by metal surface treatment. About the specifications of the chromatic color, We could develop a chromatic interference color by treatment agent We prescribed newly. Different colors such as blue, yellow, green appealed, and the color tended to depends on treatment time. The corrosion resistance of these samples was higher than that of a zink plated steel sheet. About the specifications of the achromatic color, we could give gray and a black spangle design to zink plated steel sheets. Corrosion resistance of some samples was higher than a steel sheet treated by a phosphoric acid zinc agent or a metal surface treatment agent on the market.
