Wear of advanced cemented carbides for metalforming tool materials

Wear behavior of some advanced cemented carbides (TiC-base cermets and some WC-hardmetals) in a series of functional wear experiments (including blanking of electrotechnical sheet steel in production conditions) was analyzed. Comparative laboratory trials of related materials in abrasive-erosion and adhesive-wear conditions were conducted, complemented by SEM. A good correlation between adhesive-wear resistance of the alloys investigated and their resistance to side wear (flank wear of blanking tool) as well as similarity in the morphology of surface failure in both cases was found. With regard to blanking performance, TiC-base cermet with a Ni–steel binder proved to have advantages over conventional WC-base hardmetals (used in metalforming).
