Abstract:
Binderless carbide has higher hardness, higher Young’s modulus, while the corrosion resistance and wear resistance are improved greatly compared to conventional WCCo alloy. Because there is no metal binder phase in the carbide, binderless carbide is very difficult to sinter. But with the advanced sintering technology’s invention,such as hot isostatic pressing (HIP), spark plasma sintering (SPS), and the development of submicro, nano powder manufacturing technology, pure WC, WCTiCTaC, WCSiC, WCMoCSiC and other binderless carbides have emerged. These materials are gradually used in some fields requiring high precision, high hardness, high Young’s modulus and high corrosion resistance, such as precision optical mould, blast nozzle, nuclear industry seal,etc. In this paper, we introduced several binderless carbides and their applications, and has made a simple prospect for future development.
