| 摘 要： | 研究了钕铁硼永磁材料电沉积Ni-P合金非晶态镀层的镀液组成、工艺参数和工艺流程，分析了影响镀层性能的影响因素，包括电流密度、温度、镀液pH值及亚磷酸的含量等。测定了镀层与基体的结合强度；用中性盐雾试验评定了镀层的耐蚀性。结果表明，Ni-P非晶态镀层导磁率高，矫顽力低，化学稳定性好，耐蚀性优异，是钕铁硼永磁材料的一种理想保护镀层。

| Abstract: | Cailiao baohu 2001,34(2),21∽ 22(Ch). The technological process and parameters for amorphous Ni-P alloy plating of Nd-Fe-B permanent magnetic materials were described. The factors affecting the quality of coating including current density, temperature, pH value and phosphorous acid content were discussed. It was shown that the coating was good in adhesion and corrosion resistance. |
