Research and Application of Chemical Plating Technology for ZX -01 Nickel Phospher Alloy

Combined with the features of components in heavy duty motor vehicles, a chemical plating technology for nickel phospher alloy with a superior performance has been researched and developed. The effect law of main components in plating solution and main processing parameters on plating coat is studied by using orthogonal test method. The complexing agents, buffers and stabilizing agents are compared and screened, the optimum formula and process are optimized. The process is a simple operation, the comprehensive performance of plating coat is better, the plating soution has a good stability and a longer service life. It is shown by actual application that chemical plating technology for ZX - 01 nickel phospher alloy can be used fully in production, substituting for previous electrogalvanizing and chrome - plating processes.
