| 摘 要： | 以获得含铁量为２０％的镍铁合金镀层的电镀工艺为基础，详细地研究了在镀液中引入稀土氧化物后对镀层耐蚀性能的影响．实验结果表明，稀土元素能够在阴极表面发生特性吸附，增大阴极极化，在电结晶过程中细化晶粒，显著提高镀层的耐蚀性．

| Abstract: | The effect of rare earth oxides added to the basic electrolyte on the corrosion resistance of the coatings is described in details based on the technique of 20% Fe Ni alloy electroplating. The results show that the rare earth elements possess the capability of (1) adhering tightly to the surface of cathod; (2) increasing cathodic polarization; (3) reducing the grain size during electroplating; (4) improving the corrosion resistance considerably. |
