电化学合金化Y-Cu体系的生成自由能

杨绮琴 , 刘冠昆 , 刘泽锦

金属学报

本文研究了在NaCl-KCl-YCl_3熔体中,电化学合金化Y-Cu体系的热力学行为。用恒电位电解断电后的电极电位-时间曲线测定了形成YCu_6,YCu_4,YCu_2,YCu等金属间化合物反应的ΔG(973-1103K),结果表明测量方法简单可靠。

The electrochemical alloying of Y-Cu system in molten NaCl-KCl-YCl_3 has been investi- gated.The free energy changes of the formation reactions of the intermetallic compounds,in- cluding YCu_6 ,YCu_4 YCu_2 ,Yfu(973—103 K),were determined by means of electrode potential-time curves of the working electrode after potentiostatic electrolysis.The results in- dicate that the potential-time method is simple and reliable.
