PRODUCTION OF CARBIDE AND CARBONITRIDE POWDERS CONTAINING BINDER, AND CERMET THEREFROM

摘要

PURPOSE: A synthesizing method of carbide and carbonitride powder and a cermet obtained by the same are provided to easily manufacture cermet with a uniform composition by uniformly mixing carbide and carbonitride with metal components in advance. CONSTITUTION: A synthesizing method of carbide and carbonitride powder comprises a step of preparing Ti-Ni allow powder and graphite as Ti alloy powder(ST110); a step of planetary pulverizing the Ti-Ni alloy powder and graphite(ST120); a step of mortar pulverizing the alloy powder and graphite(ST130); and a step of heat-treating the Ti-Ni alloy powder and graphite(ST140). The composition of the Ti in the Ti-Ni alloy powder is 65-88wt%. The molar ratio of Ti and graphite in the Ti-Ni alloy powder is 1:1. The synthesizing method provides carbide and carbon nitride/metal composite powder with TiC and Ni. Cermet is formed from the composite powder.
