| Abstract: | The process of alkaline non-cyanide copper electroplating on steel substrate was studied using citrate as complexing agent and amine compound as assistant complexing agent. The effects of agitation mode, temperature, pH, copper ions concentration and additive content on deposit quality were discussed. The ability of bath to resist impurities such as Fe2+, Fe3+, Zn2+ and Sn4+ was revealed. The test results showed that the current efficiency is about 90% and is increased with increasing current density, tempe... |
