| Abstract: | Recent years, considerable attention has been given to binderless cemented carbide at home and abroad for its superior wear and erosion resistance to cemented carbide. This paper has summarized the present status of research and development activities in this field. The methods of manufacturing binderleas cemented carbide are introduced in detail,such as vacumn sintering-hot isostatic pressing, hot pressing, gas sintering, spark plasma sintering, plasma pressure compaction. The superior properties of this alloy are compared with cemented carbide. Several problems of developing this hard material are pointed out. |
