抄録

Electrodeposition was performed in an unagitated solution from a urea-based melt bath containing Co and La under galvanostatic (10-40 mA·cm -2) and coulostatic (10 C·cm -2) conditions at 403 K, and the structure of the deposits was investigated. Co deposited in a metallic state at 10 mA·cm -2, whereas it was incorporated into deposits mainly as an oxide at high current densities of 30 and 40 mA·cm -2. La codeposited with Co as an oxide irrespective of current density. The content of La2O3 increased with current density. The deposits showed a granular crystal structure and became nonuniform crystals comprising large localized granules at high current densities.
