The annealing of TiC-coated carbon black in N2 at 1000–1300 °C resulted in formation of a TiCxNy solid solution, grain growth and removal of nanocracks in coatings, which significantly increased the commencement and completion temperatures of carbon oxidation, effectively improving their oxidation resistance.
