黄铜着粉红色新工艺

A New Pink Coloring Technology for Brass

介绍了一种黄铜着粉红色的新工艺。研究了时间、温度、硫酸铜和氯化铵对着色效果的影响。得出最佳的工艺配方为:硫酸铜100g/L,氯化钠25g/L,氯化铵200g/L,酒石酸25g/L,60℃,2min。最后用电化学工作站检测了着色黄铜的耐蚀性。

A new pink coloring technology for brass was introduced. The effects of time, temperature, copper sulfate and ammonium chloride on coloring effect were investigated. The determined optimum process formula was copper sulfate 100 g/L, sodium chloride 25 g/L, ammonium chloride 200 g/L, tartaric acid 25 g/L, temperature 60 ~C and time 2 min. The corrosion resistance of coloured brass was tested by electrochemical workstation.
