AA6082-T6 aluminium alloy is a candidate material, specifically in aviation applications, which could be exposed to solid particle erosion. Solid particle erosion occurs due to repetitive high-speed impact of erodent particles on a target material. Every individual impingement of the erodent particle results in elastic/plastic deformations and material removal from the target material. In this study, solid particle erosion investigations were carried out under 1.5 and 3 bar with 60 and 120 mesh alumina particles. Both erosion rates and worn volumes of the samples were calculated and measured. Also, the authors present the plastic deformation rate in this study as a proportion of the actual (measured) worn volume to the equivalent volume of the mass loss. In addition, the average surface roughness of the samples were investigated, which is another parameter for understanding the effect of plastic deformation on surface properties during particle erosion.
