Ground Surface of Y-TZP

Abstract

A monoclinic phase is frequently seen on fractured surfaces of yttria stabilized tetragonal ZrO₂ polycrystals (Y-TZP). In this study, Y-TZP materials were ground by diamond grinding wheels of different grain sizes and the effects of grinding on the structure in the surface layers was examined from the viewpoint of the grinding mechanism. It was found that a compressive layer was formed on the ground surface and bending strength was increased by grinding under specific conditions.
