绿色环保型BFe10-1-1铁白铜化学抛光工艺研究

Environment-friendly Chemical Polishing Technology of BFe10-1-1 Copper Alloy

研究以H2O2为主要氧化剂的化学抛光液对BFe10-1-1铁白铜进行表面化学抛光,考察了光亮剂、缓蚀剂、H2O2稳定剂的种类,化学抛光液各组分的含量,抛光温度以及抛光时间对铜合金抛光效果的影响。优化出抛光液组成及抛光工艺条件:质量分数为30%的H2O2350mL/L,浓H2SO450mL/L,无水乙醇17～20mL/L,OP-10 1mL/L,苯骈三氮唑(BTA)1g/L,水余量;在50℃下抛光3～5min。

Taking H2O2 as main oxidant, the process of environment-friendly chemical polishing of BFel0 1 1 copper alloy was investigated. The influence of type of brightener, type of corrosion inhibitor, type of stabilizer of hydro gen peroxide, the polishing solution composition and polishing condition including polishing temperature and polishing time on the surface quality of the polished BFel0-1-1 copper alloy was discussed, and processing condition was opti mized. The optimum composition of the chemical polishing solution for the BFel0-1 1 copper alloy was recommended to be composed of 350 mL/L hydrogen peroxide （30%）, 50 mL/L sulfuric acid, 17-20 mL/L ethyl alcohol, 1 mL/L OP 10, and 1 g/L 1,2,3 Benzotriazole, while the optimized polishing condition was suggested as temperature about 50℃ and polishing time 3-5 min.
