Abrasive wear behaviour of conventional and large-particle tungsten carbide-based cermet coatings as a function of abrasive size and type

► Dry sand rubber wheel and micro-scale abrasion wear of conventional and large carbide cermets. ► The relative scales of microstuctural features and abrasive determine wear mechanisms. ► Low micro-scale abrasion wear occurs if the mean free-path and abrasive are of similar size.
