The future trend of steel bonded cemented carbide

Issuing time:2018-02-22 00:00

The relationship of the composition, microstructures and performance has been systematically elaborated. The main preparation technology of steel bonded carbide is summarized, and it is pointed that the powder metallurgy has been widely adopted to produce steel bonded carbide. However, due to the lower cost and better performance, electroslag melting and casting, self-propagating high temperature synthesis(SHS) and carbothermal reduction methods are full of vitality. In addition, forging and heat treatment can effectively improve the structure and performance of the alloy; Boriding, boron-sulphurizing treating process and laser cladding process can improve the surface hardness, reduce the friction coefficient and increase the service life. Finally, the development trend of steel bonded carbide is prospected.
