Abstract

Carbon films on ceramic surfaces can impart useful properties for corrosion, wear, and other applications. Because of the low thermodynamic stability of carbon-chlorine compounds and the volatility of metal chlorides, such films can be formed on metal carbides by high temperature reactions with chlorine. Thermodynamic calculations and Raman spectroscopy measurements have been used to characterize the carbon films formed on a number of metal carbides.
