通过扫描电镜、电化学分析和腐蚀失重等方法，研究了镀液中添加RE对双脉冲电沉积法获得镍镀层的耐蚀性影响。结果表明：镀液中添加适量的RE，可使镀层组织细小且表面平整致密，耐蚀性提高，当镀液中含RE量为0.25 g/L时，镀层耐蚀性较好。
The effect of adding RE to plating bath on corrosion resistance of Nickel coatings prepared by pulse reversal current electrodeposition was studied by means of SEM/EDS, electrochemical analysis and corrosion mass loss. The results showed that adding proper RE to plating solution can promote the surface smoothing and the crystal fineness, and also improve the corrosion resistance. The coatings exhibited the higher corrosion resistance when the concentration of RE reaches 025 g/L.
