不腐蚀

The main work of this thesis is to research the sulphate bath, we find that the sulfate system has the advantage of slight acidic choloride electrolyte system and alkaline zincate system. The solution of sulphate system is very simple and easy to maintain and high current efficiency. Furthermore, the technology has the advantage of lower plating cost and broader width of the temperature.
