【Abstract】 In this artical, the process of Cr³⁺electroplating on oxalic acid system is studied with the method analysing the influence of operation conditions on current effiency and coating thickness. The effect about compositions of solution are also described in detail. Testing results on performences of solution and deposit show: this process has high current effiency, fine stabilize property, remarkable increasing in thickness, achieving 7.1 μm with continuous plating.更多还原
