Aluminum alloys are one of the most common materials used in aircraft structural part production. Moreover, high cruising speeds of aircrafts resulted with high velocity impacts of micro hard particles such as dust, fly ash, impact ice and rain droplets. These hard particles involved in atmospheric air concentration cause repeated impacts on surface Extruded AA6082-T6 aluminum alloy sheets were subjected to solid particle erosion tests. Solid particle erosion tests were performed according to ASTM G 76 standard. Abrasive particles with various particle sizes blasted to surfaces of AA6082-T6 aluminum alloy test coupons. Solid particle erosion tests accomplished at normal incidence (impact angle:90°) with blast pressure of 3 Bar. Average roughness (Ra), average distance between the highest peak and lowest valley in each sampling length (Rz) and 3D surface topography maps and erosive wear rates of AA6082-T6 aluminum alloy test coupons were obtained before and after solid particle erosion tests. Correlations between erosion crater volume and mass loss were discussed.
