The three dimensional shape effect of asperity on abrasive wear was investigated with in-situ experiments in the scanning electron microscope. The geometry of model asperity was represented by attack angle and dihedral angle, where attack angle changed in 0-90 deg and dihedral angle in 0-180 deg. Wear modes of shearing, cutting, and wedge forming were observed and each mode was related to attack angle and dihedral angle by wear mode diagram. Wear rate in cutting mode increased with attack angle and was maximum at a certain dihedral angle.
