| titleOfInvention | Functionally graded cemented tungsten carbide with engineered hard surface and the method for making the same |
| abstract | A method for manufactur-ing functionally graded cemented tungsten carbide with hard and wear-resistant sur-face and tough core is described. The said functionally graded cemented tungsten car-bide (WC-Co) has a surface layer having a reduced amount of cobalt. Such a hard sur-face and tough core structure is an example of functionally graded materials in which mechanical properties are optimized by the unique combination of wear-resistance and toughness. WC-Co with reduced-cobalt surface layer may be fabricated through a carburization heat treatment process fol-lowing conventional liquid phase sintering. The graded WC-Co thus obtained contains no brittle .eta. phase. |
