In this study an attempt has been made to evaluate the solid particle erosion behavior of PVC based composites with various volcanic ash (VA) concentrations (5, 10, 15, 20 and 25 wt.%). VA/PVC composites were prepared by using a twin screw micro-compounder and an injection molding machine. The erosion testing of VA/PVC composites was performed in accordance with the ASTM G76-95 standard at 6 different particle impingement angles (15°, 30°, 45°, 60°, 75° and 90°) and under the pressure of 1.5 bar by using abrasive Al₂O₃ particles. The morphology of eroded surfaces was examined by using a scanning electron microscope (SEM), and possible wear mechanisms were discussed. Moreover, the surface roughness values of eroded VA/PVC composites were analyzed by using a non-contact laser optical profilometer. 3D surface topographies were also examined.
