Wear behaviour, durability, and cyclic strength of TiC base cermets

This article describes the wear and mechanical behaviour of TiC base cermets studied by durability tests, including testing of blanking performance and fatigue endurance. Comparative laboratory trials in the abrasive erosion, sliding, and adhesive wear conditions were conducted and complemented by SEM studies. It was found that the blanking performance (durability during blanking of sheet metals) of a carbide composite (hardmetal, cermet) is controlled by its resistance to adhesive wear, and origin and propagation of fatigue cracks (fatigue damage).
