摘要
The preparation of Ni-P/Ni3.1B composite alloy coating on the surface of copper was achieved by co-deposition of Ni3.1B nanoparticles with Ni-P coating during electroless plating.Ni-P-B alloy coating was obtained by heat-treating the as-plated Ni-P/Ni3.1B composite coating.The effect of the concentration of sodium alginate, borax, thiourea, Ni3.1B, temperature, and pH value on the deposition rate and B content were investigatedand determined to be: 30 g L-1, 10 g L-1, 2 mg L 1, 20 mg L-1, 70 ℃ and 9.0 , respectively.Sodium alginate and thiourea were played as surfactant for coating Ni3.1B nanoparticles and stabilizer for the plating bath, respectively.Ni-P/Ni3.1B composite coating had good performance such as corrosion resistance and solderability.
