The effect of Cobalt Replacement by Nickel on Microstructure, Physical and Mechanical Properties of WC-Co Hardmetals, M.Sc. Thesis Sharif University of Technology ; Pourazerang, Kazem (Supervisor) ; Abachi, Parvin (Supervisor)
Abstract
WC-Co hardmetals that are produced through powder metallurgy rout are vastely used as wear resistant parts. In these materials hard particles of wolfram carbide are embodied in a cobalt binder. Because of their high hardness and adequate toughness, hardmetals have found wide range of applications in cutting tool industry. During the last decades a number of researches have been carried out to improve their mechanical and wear properties by different binders and carbide particle sizes. Because of high hardness, Tungsten carbide has a good wear resistant. It has very low thermal expansion coefficient and high wetting ability with molten metals. Unlike high hardness, it has limited toughness....
