【摘要】 用恒电流电解法在乙酰胺－尿素－溴化钠熔体中电沉积出Ｙ的质量分数（ｗ（Ｙ））高达８７．５０％的Ｙ－Ｎｉ合金，在铜片上获得附着力强的合金薄膜．实验结果显示电沉积出的Ｙ－Ｎｉ合金中的。ｗ（Ｙ）随着电流密度增大而增大．在低电流密度获得的是带有金属光泽的银白色合金薄膜，在高电流密度获得的是黑色的合金薄膜更多还原

【Abstract】 The codeposition of Y-Ni alloy on Cu electrodes was investigated in acetamide-urea-NaBr melt containing YCI3 and NiC12 at 353 K. Galvanostatic electrolysis was used to prepare the Y-Ni films. The films with strong adhesion on Cu were obtained. The experimental results also show that the content of Y in Y-Ni increases with the increasing of current density. The films obtained at low current density are silver with metallic lustre while at high current density it is in black color.更多还原
