The wear behavior of TiCN cermets was investigated under water-based slurries with coarse angular abrasives of SiC, Al2O3 and SiO2, through a modified ASTM B611 wet-sand rubber-rimmed wheel test system. Under the same conditions, the wear rate increased with increasing abrasive hardness and mass fraction. With increasing sliding distance, under lower abrasive fraction the wear rate increased very slowly, but under higher abrasive fraction it initially increased rapidly, then became steady and even dropped down. Through observing the abraded sample surfaces by 3D white-light interfering surface profiler, the wear mechanism of TiCN cermets was proposed. (C) 2013 Elsevier Ltd. All rights reserved.
