The fracture toughness KIC of cemented carbide (WC-Co) coated with TiN or TiC by PVD was measured by the Vickers hardness indentation method. It was found that the fracture toughness of the TiN-coated specimens showed a tendency to decrease with annealing at 1273K in a vacuum, whereas that of TiC-coated specimen increased.
