The TaC coatings were prepared by precursor slurry application and subsequent sintering processes on graphite substrate. The prepared coating were investigated with their phase composition and morphology, by means of XRD and SEM. The coating consisted of single-phase TaC and had a dense granular structure containing grain with the mean size of 12μm. The coating had an isotropic granular structure, which make the crack tip would be pinned at a grain boundary junction and would not fully penetrate the coating. The hardness and the plastic modulus of the coating are 15.35GPa and 195.1GPa, respectively.
