摘　　要：采用化学镀制备Co-Pt-Mo合金镀层,研究了pH值及温度对镀层表面形貌、成分和磁性能的影响。结果表明:随着pH值的升高,镀层中钴的质量分数增加,致使镀层的比饱和磁化强度增大;温度对镀层的成分及矫顽力并无影响,但是温度过高时反应速率过快,致使镀层表面出现"孔洞"。A Co-Pt-Mo alloy coating was prepared by electroless plating, and the effects of pH value and temperature on the surface morphology, composition and magnetic performance of the coating were investigated. The results show that as pH value goes up, the mass fraction of the cobalt in the coating increases, causing an increase in specific saturation magnetization of the coating; temperature has no impact on the composition and coercive force of the coating, but when temperature is too high,the reaction rate is also too fast, resulting in pores in the coating surface.
