The influence of high temperature oxidation on the Vickers hardness of a cemented carbide, tungsten carbide (WC) added with cobalt (Co), was investigated in order to determine its suitability for improvement hardness. The Vickers hardness of WC-Co was improved by high temperature oxidation treatment. The oxidation thickness of the sample from 973 to 1273 K depended on oxidation temperature and time. The oxidation thickness increased with increasing oxidation temperature and time, especially, significant oxidation of samples occurred at 1073 K.
