摘　　要：以不锈钢为基体,采用化学镀方法制备Ni-P合金,然后在镀液中添加TiO_2纳米粒子制备出低磷化学复合镀Ni-P合金,以镀层硬度、孔隙率、磷含量、沉积速率等为评价指标,研究了TiO_2纳米粒子对低磷化学复合镀Ni-P合金的影响。结果表明,镀液中添加纳米TiO_2后,镀层硬度增大、孔隙率降低、磷含量增加。TiO_2纳米粒子的最优添加量是0.50 g/L。Ni-P alloy was prepared on stainless steel substrate by electroless plating method. The TiO2 nanoparticles were added in the solution,and low phosphorus Ni-P alloy was prepared by electroless composite plating technique. The effect of TiO2 nanoparticle on the low phosphorus electroless composite plating of Ni-P alloy was studied using the hardness,porosity,phosphorus content and deposition rate of the coating as evaluation factors. The results showed that the hardness of the coating increased with addi tion of TiO2 nanoparticles into the bath,as well as the decrease of porosity and the increase of phospho rus content. The optimum TiO2 nanoparticles addition amount was 0.50 g/L.
