DIAMOND-CLAD HARD MATERIAL AND METHOD OF MAKING THE SAID MATERIAL |
摘要 |
A diamond-clad hard material whose base component is of WC-group cemented carbide, and a method of making said material. The material is characterized by being provided on the outermost surface of said base component with a surface modified phase containing no binding phase or a binding phase whose compositional ratio is lower than that in the inner part of the base component. The base component can be turned into a final product when coated with diamond after sintered or heat-treated at skin thereof. The hard material is exceedingly high in resistance-to-wear an excellent in adhesiveness to the base component, and thus can advantageously be used for various kinds of tools, parts or grindstones. <IMAGE> |
