Notes:
The effect of TiC content on oxidation behavior of the sintered WC-TiC-TaC alloys with2 mass% TaC and different TiC amount of 3-45 mass% was investigated through oxidation tests inair at 973K in order to clarify their oxidation mechanism at high temperature. Based on the resultsof mass change, SEM observation, elemental map analysis and composition analysis of the samplesbefore and after the oxidation test, it was revealed that with increasing TiC content in the alloys,mass changes from oxidation and thickness of the oxidation scale decreased. Thus, it is consideredthat the main component of the scales changed from WO3 to TiO2 gradually with increasing TiCcontent in the alloys, and oxygen diffusing through the oxidation scale to the alloys was inhibitedmore and more
