摘要
研究了稀土元素铈(Ce)对光亮镍镀液电流效率、分散能力和阴极极化能力的影响:测试了所得光亮镍镀层的表面形貌和镀层的硬度以及在5%NaCl溶液中的阳极极化曲线,讨论了稀土元素Ce对镀层性能的影响。结果表明,Ce^(3+)的加入对电流效率影响不大,但提高了镀液的分散能力和阴极极化能力:Ce^(3+)的加入可以使镀层晶粒细化,从而提高了镍镀层的硬度和耐蚀性。
In this paper, the effect of rare earth element Ce on the electric current efficiency, the dispersion ability and the cathodic polarizing of the nikel layer surface morphology, the nikel layer hardness and the nikel layer was studied. Tafel curve in the 5% NaCI aqueous was tested. The result shows that Ce^3＋ has little effect on electric current efficiency, howerver, the dispersion and the cathodic polarizing ability are improved. The crystal grain of the nikel electroplate dwindle in sice are dense, the nikel layer hardness and causticity-resistant are improved because of adding Ce^3＋.
