Abstract

Concerning the effects of erosive particle size and impact angle on the wear rate and surface residual stress, the impact damage behavior of injection molded Cr₃C₂/Al₂O₃ composites was investigated. The experiments were performed using a gas-blast erosion rig with SiC and Al₂O₃ erodents. The results suggest that the larger erodent particles are more effective in displacing and damaging the surface compared to the smaller particles, and lead to higher wear rate and surface residual stress. The variation in surface residual stress with kinetic energy is consistent with the erosion rate and post-erosion strength.
