Abstract
This invention relates to a formula of Ni-P/Au plating solution for nanoscale composite chemical plating layer. The formula comprises: nickel sulfate 12500-15000 parts, sodium hypophosphite 12500-15000 parts, sodium acetate 10000-15000 parts, sodium citrate 12500-15000 pars, stabilizer 1.5-2 parts, and gold nanoparticles 0.01-1 part. The addition of aqueous solution of gold nanoparticles can protect the stabilizer, and prevent the aggregation of powder in the plating solution. Besides, the two aqueous solutions are completely compatible, thus gold nanoparticles can be uniformly dispersed in the plating solution. The plating temperature of the plating solution is 10 deg.C lower than that of base plating solution, and can obtain plating layer with higher thickness, higher hardness, better corrosion resistance and better wear resistance in the same plating time. Therefore, the plating solution can save energy, and increase the cost performance of the plating layer.
