TiC-reinforced coatings promise to be an excellent replacement for WC/Co and Cr{sub 3}C{sub 2}/NiCr carbide reinforced thermally sprayed coatings. TiC-containing coatings (up to 90 v/o) are lighter, less expensive and offer lower friction coefficients than these two standard industrial thermal spray coatings. TiC reinforcing phases, however, may be less stable during plasma spraying and may react or decompose during processing or in operation. Investigations into the compatibility of TiC in Ti, TiNiCrAl and FeCr matrices have been conducted and the results of plasma spray processing will be presented. Powders that have been evaluated were produced via mechanical mixing and by self-propagating high-temperature synthesis (SHS). Resultant coating structures, properties and comparative sliding wear resistance will be reported.
