Beschreibung
Zusammenfassung:	The fast colorizing process for stainless steel surface includes the pre-treatment of the surface, the colorizing, and the sealing treatment of the color film. The present invention has the features of colorizing solution with six-valent Cr ion concentration as low as 10 % of that in Inco process and its derived process, relatively low colorizing temperature, low toxicity, low power consumption, greatly lowered colorizing cost and environmental pollution. The color film is compact, flat, strong in combination with stainless steel base, wear resistant, corrosion resistant, color fast, and suitable for anticorrosive protection and decoration.
