摘要：

The erosive wear resistance of WC and TiC-base hard metals with different composition, structure and properties has been investigated. It has been shown that hard metals erosive wear resistance cannot be estimated only by hardness, characterizing resistance to penetration (i.e. large local plastic strains). The difference in wear resistance between hard metals with equal hardness level can be attributed to differences in their resistance to fracture. The best evaluation of erosive wear resistance is obtained by means of combined factors defined by the product of strain and fracture resistance.
