Abstract
⺠Decreasing the friction coefficient is effective in preventing microcracks. ⺠AFM and SEM observations confirm that edge crack is initiated from porosity and roughness grooves. ⺠Rougher surfaces show higher stress concentration coefficient than smoother surfaces. ⺠Lubrication reduces the frictional stress, and crack initiation is delayed for finer surfaces.
