| Popis: | 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 TiC x in the homogeneity range (x = 0.5–1.0). The content of TiO and TiO2 tends to decrease in the surface film on all compounds in the TiC0.6 → TiC1.0 row, with a very small amount of the TiO2 phase in the scale. 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. |
