Solid particle erosion behavior of AA 6061 aluminum alloy was evaluated using a recently developed erosion wear test system. Wear tests were performed under different impact angles (20, 30, 45, 60, 90 degrees) and velocities (74, 90, 150, 195 m/s) at ambient temperature. Alumina particles with 50 micron in dimension were used as erodent. Results showed that higher the impact velocity the higher the erosion rate is obtained. On the other hand, the highest erosion rate was recorded for the impact angle of 20 degree Optical microscopy images revealed that several mechanisms such as plastic deformation and ploughing involved in erosion behavior.
