Electrochemical deposition of La-Mg alloys in LaCl3-MgCl2-KCl system with molten salt electrolysis process
La-Mg alloys of different compositions were prepared by electrolysis of LaCl3-MgCl2-KCl melts. Different phases of La-Mg alloys were characterized by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Energy dispersive spectrometry (EDS) and Inductively Coupled Plasma-Atomic Em...

| Summary: | La-Mg alloys of different compositions were prepared by electrolysis of
LaCl3-MgCl2-KCl melts. Different phases of La-Mg alloys were characterized by
X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Energy
dispersive spectrometry (EDS) and Inductively Coupled Plasma-Atomic Emission
Spectroscopy (ICP-AES) analyses showed that chemical compositions of La-Mg
alloys were consistent with phase structures of XRD pattern, and magnesium
content in the alloy could be controlled by electrolysis parameters. The
effects of various process parameters such as concentration of magnesium
chloride in the bath, temperature of electrolysis and cathode current density
on the current efficiency have been investigated. A maximum current
efficiency of 85% and yield of 80% was obtained from the bath at 12.5A/cm2
current density at an operating temp 850°C. |
