| Abstract | An important carbon loss occurs during the plasma spraying of TiC in air and, to a lesser extent, in an inert atmosphere. Moreover, an increase in the oxygen content is observed in coatings sprayed in air. In the present study, different carbon coatings were applied to TiC powders by an agglutination coating technique in order to control both the carbon stoichiometry and the oxygen content within sprayed coatings. The effects of the carbon crystalline form (graphite or carbon black) and of the coating weight percentage deposited on TiC particles on the chemical composition and microstructure of plasma-sprayed coatings were investigated. An increase in both combined and free carbon content and a decrease in the oxygen contamination were observed in coatings sprayed in air with the carbon-black-coated TiC powders. On the other hand, graphite coatings applied to TiC particles had a less significant effect on the composition of coatings sprayed in air or in the inert atmosphere. Severely decarbonized and oxidized zones were found within coatings sprayed in air. |
