| 摘 要： | 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Ni-Co合金镀层的组织和耐蚀性的影响.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0.25g/L时,镀层耐蚀性最好,并对RE提高镀层耐蚀性的原因进行探讨.

| Abstract: | The effect of adding RE to plating bath on microstructure and corrosion resistance of Ni - Co alloy coatings prepared by puLse reversal current electrodepesition was studied by means of SEM/EDS, electrochemical analysis and corrosion mass loss etc. The results showed that adding proper RE to plating solution can promote the microstructure of coatings compacter, the surface smoother and the crystal finer, as well as improve the corrosion resistance. The coatings exhibited the highest corrosion resistance when the concentration of RE reaches 0.25 g/L. In the paper, the reason of increasing corrosion resistance by adding RE was also investigated. |
