| 摘 要： | 在铝及其合金表面沉积Ni或Ni基合金,可以提高基体表面的硬度和耐磨性.通过正交试验,研究了铝硅合金基体上电镀Ni-Co-P镀层的工艺,得到了电流密度、镀液温度、pH值、电镀时间、镀液成分对镀层厚度、硬度、成分和沉积速率的影响规律,同时,还考察了镀层的耐磨性.结果表明:延长电镀时间、提高镀液温度和pH值时,镀层厚度和镀层硬度均增大;提高电流密度时,镀层厚度增大,但镀层硬度减小.提高电流密度、升高温度和提高pH值时,沉积速率增大.

| Abstract: | Orthogonal tests were carried out to investi-gate the process for electroplating of Ni-Co-P alloy coating on hy-per-eutectic Al-Si cast alloy.The effects of electric current den-sity,temperature,plating time,and pH value and component of electroplating bath on the thickness,hardness and deposition rate of Ni-Co-P coating were explored.And the wear resistance of the Ni-Co-P coating was evaluated.It was found that the thickness and hardness of electroplated Ni-Co-P coating increased with in-creasing plating t... |
