Abrasive Wear - an overview ScienceDirect Topics

The quantity of material removed in an abrasive wear situation is directly proportional to the distance covered by the hard particle and inversely proportional to the surface hardness. Relative resistance to wear is the inverse of the quantity of material removed.

Abrasive wear resistance of WC-based composites,

The abrasive wear-resistance decreases for higher binder contents (for a given carbide particle size). Although wear of the carbide particles may arise (the rounding of the particles is an evidence), the dominant mechanism of wear is the removal of the binder, followed by the consequent carbide pull-out, increasing the wear rate.
