Electrochemical formation of Sm-Co alloys by codeposition of Sm and Co in a molten LiCl-KCl-SmCl{sub}3-CoCl{sub}2 system

摘要

Electrocodeposition of Sm and co on a cu substrate was investigated in a molten LiCl-KCl-SmCl{sub}3 (0.5 mol.%)-CoCl{sub}2 (0.1 mol.%) system at 723 K. Phase of the deposited Sm-Co alloys could be controlled by electrolysis potential. SmCo{sub}3 was formed on a Cu substrate by potentiostatic electrolysis in the potential range of 0.20-0.90 V (vs. Li{sup}+/Li). Sm{sub}2Co{sub}17 was obtained in the potential range of 0.90-1.50 V.
