Properties of Sintered WC-(High Chromium Cast Iron) Alloys

In the case of partial application of hard materials to wear-resistant components, it is difficult to insert by casting WC-based cemented carbide. 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 cem...

Zusammenfassung:In the case of partial application of hard materials to wear-resistant components, it is difficult to insert by casting WC-based cemented carbide. 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) Sintered products with powder injection abrasion properties similar to those of sintered WC-based cemented carbide were obtained.
