| 摘 要： | 应用恒电位沉积法和循环伏安法(CV)研究碱性柠檬酸盐溶液中Ni-Mo合金共沉积规律.恒电位沉积结果表明:MoO42-的加入可以降低Ni的沉积过电位,随电位负移Ni-Mo合金的沉积电流效率逐渐低于镀Ni溶液中Ni的沉积效率.循环伏安测试结果表明:随着Ni 2+的含量增加,Ni沉积的第一个还原峰电位和Ni-Mo合金的沉积峰电位均正移;随MoO42-的含量增加,Ni-Mo合金沉积峰电位负移.

| Abstract: | The electrodeposition laws of Ni-Mo alloy in alkaline citrate solution were studied with potentiostatic deposition and cyclic voltammetry. Potentiostatic deposition indicated that the presence of MoO42- could reduce the deposition overpotential of Ni, and the deposition current efficiency of Ni-Mo alloy was lower than Ni in Ni deposition bath as the potential moved negatively. Cyclic voltammetry indicated that, as the content of Ni2+ increased, both the first reduction peak for Ni deposition and the deposition peak of Ni-Mo alloy moved to more positive potentials, and as the content of MoO42- increased, the deposition peak of Ni-Mo alloy moved to more negative potentials. |
