Abstrakt: The addition of titanium nitride and niobium carbide to the alloys based on TiC with the nickel-molybdenum binder (TN type) increases their oxidation resistance in air at high temperatures (1173-1273°K). The alloys based on the titanium carbide and nitride and alloyed with the niobium carbide with the nickel-molybdenum binder (NTN) have higher oxidation resistance in air than the commercially produced TN20 and T15K6 alloys. The equations of the kinetic curves of oxidation in air of the TN20 and NTN alloys were derived; at temperatures of 1173 and 1273°K, the curves are almost linear, starting at a holding time of 10 min.
