Abstract

The potentiodynamic polarization curves, X-ray diffraction, energy-dispersive X-ray spectrometry, and Auger electron spectroscopy are employed to study the kinetics and mechanism of electrochemical oxidation of stoichiometric and nonstoichiometric samples of titanium carbide TiCх in the homogeneity range (x = 0.5–1.0). All compounds in the TiC0.6 → TiC1.0 row tend to reduce in the surface film formed by TiO and TiO2 and a very small amount of the TiO2 phase. The stoichiometric TiC1.0 sample shows the highest resistance to anodic oxidation because it has the strongest Ti—C bonds formed completely in its lattice.
