Abstract According to the distribution characteristics of sandstorm in Inner Mongolia, using taguchi orthogonal method and erosion experiment simulation system of wind-blow sand environment to analyze the controllable factor’s stability (impact angle, impact velocity and abrasive feed rate) and the erosion performance of tempered glass. SEM and LSCM were utilized to investigated the erosion damage morphology. Result manifested that abrasive feed rate was contrary with impact angle and impact velocity,had lower S/N and more instability in the erosion experiment. Impact angle had highest rate of contribution in erosion experiment, impact velocity secondary and abrasive feed rate thirdly. In low impact angle,the micro-cutting was the main reason of mass loss and had clearly furrow on tempered glass surface in the SEM image. In high impact angle,the main reason of mass loss was crack propagation and had brittle fracture pits on tempered glass surface in the SEM image. The erosion depth and width of damage increased with the increase of impact angle, and the damage morphology become cone.
