| Abstract: | With the rapid developing of industry, cemented carbides is required higher and higher. The gradient cemented carbides can get gradient variations in properties with gradient in components or structures. Tools which made by it is obtained high hardness and better toughness. It solves the conflict between abrasive resistance and toughness of conventional cemented carbides. In this paper, the development, fabrication methods and industrial applications of gradient cemented carbides, domestic and overseas are summarized. The principle and the property of each fabrication method are also discussed simply. Finally, the prospect of gradient cemented carbides is pointed out. |
