Optimizing of Deposition Speed of Electroless Nickel Plating Coating
In order to improve deposition speed of electroless nickel plating coating, composition of complex accelerating agent was optimized by orthogonal test, and SEM and its EDS was used to analyze the plating morphology. The results show that the deposition speed is increased to 27.5μm/h after 0.002g/L of cadmium sulfate, 0.05g/L of sodium dodecyl sulfate, 10g/L of malic acid and 15g/L of butanedioic acid was mixed into an electroless plating solution. The coating holds good surface quality and its phosphorus content is 14.03%, any pore was not found on the surface and decay resistance of the coating was improved.
