ABSTRACT:
A method of manufacturing a surface-coated TiCN-base cermet material for inserts of cutting tools. A substrate of a TiCN-base cermet is prepared. Then, a hard surface layer is coated over surfaces of the substrate, the layer being formed of one of a single layer of one compound selected from the group consisting of TiC, TiN, and TiCN, and a composite layer of at least two compounds selected from the same group. In coating the hard surface layer, an ion plating method is applied under the conditions that the reaction temperature is 700.degree.-1000.degree. C., the voltage applied on the substrate (-)100-(-)1000 volts, and the pressure of the reaction atmosphere 1.times.10.sup.-5 -2.times.10.sup.-4 torr. The hard surface layer thus obtained has a mean thickness within a range from 0.5 to 10 microns and a mean grain size of not more than 0.05 microns.
