摘　　要：研究了镀液 pH 值对 Cu/Ni-P 合金镀层硬度及耐蚀性能的影响。结果表明,镀液 pH=9时,铜/镍磷双镀层具有很好的耐蚀性能和较高的硬度。The influence of pH value of the chemical plating solution on the hardness and corrosion- resisting property of the Cu/Ni- P composite coating are studied. The results show that the hardness and corrosion - resisting property of the Cu/Ni- P composite coating obtained in the plating solution with pH = 9 are optimum.

关 键 词：PH值 Cu/Ni—P镀层 耐蚀性 硬度
