Abstract

This work focuses on the abrasive wear performance of some carbide composites: WC-hardmetals and TiC-base cermets (in particular, composites prospective for metalforming). Wear tests were performed using the dry rubber-rimmed rotary wheel machine (modified ASTM 65-94 method). The results relate to the mechanical properties and structure. It is shown, that the abrasive wear of a carbide composite is controlled by its rigidity (resistance to elastic and plastic strain) and depends firstly on fraction, grain size and properties of the carbide phase, and secondly, on those of the binder.
