摘　　要：研究了在氨基磺酸盐体系中搅拌速度、电流密度、镀液中金刚石的浓度对镍基金刚石复合镀层中的上砂量以及复合镀层抗腐蚀性能的影响。由单因素试验结果表明,在搅拌速度为250r/min、电流密度为1.5A/dm^2、镀液中金刚石含量控制在15g/L时,所得复合镀层中金刚石含量为12.61%,且复合镀层均匀一致,自腐蚀电流为3.677μA/cm^2。The effects of stirring speed,current density and the diamond concentration in the plating solution on the diamond content in the nickel-based diamond composite coating and the corrosion resistance of the composite coating are investigated in a nickel sulfamate bath system.Single-factor experimental results show that the diamond content in the resulting composite coating is 12.61%,the composite coating has a uniform flatness and the corrosion current density is 3.677μA/cm^2 when the electroplating parameters are optimized at a stirring speed of 250r/min,a current density of 1.5A/dm^2 and the diamond content in the plating solution controlled at 15g/L.
