Abstract

At present, surface hot coloring technology has gradually become the main coloring technology in copper crafts industry. However, the process of imitating gold on brass surface has not been reported. In this work, a hot coloring process of imitating gold on brass products was introduced, and the factors affecting coloring, such as chemical formula, coloring temperature, coloring time and brass material were analyzed. The surface hot coloring process of brass was as follow: 8～15 mL/L water - based yellow metal complex dye, 2～5 g/L sodium dichromate, 1～2 g/L tartaric acid, 0～5 g/L citric acid, 0.1～0.3 mL/L JFC penetrant, 10～20 mL/L alcohol (95%), a heating temperature of 120～200 ℃, 30～50 times of spraying or brushing. Results showed that the imitation gold brass product made through this process had transparent and uniform color, good adhesion and imitation gold effect, and the process was simple and environmentally friendly.
