| Abstract: | Several non-cyanide electroplating processes,including pyrophosphate copper electroplating,neutral nickel electroplating,organophosphate copper electroplating and tartrate copper electroplating,as well as electroless nickel plating processes with pyrophosphate and citrate systems for zinc alloy die-castings were introduced. The difficulties and existing problems such as adhesion strength,black spot and brightness for non-cyanide surface treatment of zinc alloy die-castings were analyzed. |
