摘要：

The Conventional Titania (TiO2) and Titania blends with 10% SiC powder was thermally sprayed on commercially pure titanium substrate using High Velocity Oxy-Fuel (HVOF) spraying. The microhardness value of these coatings was measured by Vickers microhardness tester. The coating porosity, cross sectional morphology and wear surface morphologies was observed in Optical Micrograph (OM) and Scanning Electron Micrograph (SEM). The X-Ray Diffraction analysis was made to observe the phase composition of these coatings. The wear behavior of these coatings was studied in Pin-on-Disk arrangement as per ASTM G99 standard. It was found that addition of SiC enhances the hardness and wear resistance of the coating. Further, wear surface morphology was analysed and possible wear mechanisms were discussed.
