Abstract

The titanium carbonitrides, Ti(C, N), with different C/N ratios were coated on HIP-treated WC-Co substrates by PVD process at 773 K. The transverse-rupture strength of coated specimens and the properties such as hardness and resistance to oxidation of coated layer were studied in relation to C/N ratios. The hardness of coated layer decreased with decreasing C/N ratio. The strength of coated specimens was not almost affected by C/N ratios. The abrupt decrease in the strength was observed, when the specimens were annealed at temperature of about 1173K. This showed that each layer was lacking in the thermal stability. It was found that the resistance to oxidation of the layer varied according to C/N ratios, and it became worst at C/N ratio of 2/8. A further study on this subject, however, is needed.
