摘要
Scratch experiments were performed on MgO (001) plane along different crystallographic orientations with the gradually increased forces to investigate the deformaton and damage of MgO. The normal and lateral forces during scratch, as well as the topography characteristics of the residual scratch along different crystallographic orientations were compared and analyzed. The cracks propagation around the scratch were studied. The patterns of cracks and scratches were found to be very different when scratching along different crystallographic orientations. The mechanism of cracks forming beside the scratches on single crystal MgO was discussed.
