In the case of partial application of hard materials to wear-resistant components, it is difficult to insert by casting WC-based cemented carbide. In order to solve this problem, we studied WC- (high chromium cast iron) alloys that applied high chromium cast iron instead of cobalt as a binder of WC-based cemented carbide.
We conducted studies on the manufacturing method, mechanical properties, and powder abrasion properties of this WC- (high chromium cast iron) alloy and obtained the following results.
(1) Sound sintered products were obtained by sintering in a pressurized nitrogen atmosphere.
(2) Sintered products with a hardness similar to that of sintered WC-based cemented carbide were obtained.
(3) Sintered products with a flexural strength similar or superior to that of high chromium cast iron were obtained.
(4) Sinterd products with powder injection abrasion properties similar to those of sintered WC-based cemented carbide were obtained.
