摘要：

Electrodeposition of carbon on an aluminum electrode was studied in a LiCl-KCl-K2CO3 melt. A cyclic voltammogram for an aluminum electrode indicates that the cathodic current is due to the reduction of CO32- ions. Carbon films on aluminum substrates were obtained by potentiostatic electrolysis, and the cohesiveness of the films depended on the potential. SEM observations showed that the morphology of the deposited carbon film depends on the electrolytic conditions. Raman spectroscopy, XPS and XAES measurement showed that the film consisted of carbon in the sp(2) state.
