Department of Materials Science and Engineering, Jilin University of Technology, Changchun 130025, P. R. China

Abstract:Amorphous Al-Mn electrodeposition on steel plate was obtained with a molten salt. It was shown that during the electrodeposition, current efficiency, electrodeposition composition, electrodeposition structure and electrodeposition thickness are influenced by current density during the electrodeposition; as the current density increases, Mn content in the electrodeposition decreases; the thickness of the plating layer increases as the current density increases in a certain range; the current efficiency is up to its maximum (90%) when the current density is 45 mA/cm2.

 

Key words: current density amorphous Al-Mn electrodeposition composition of electrodeposition
