AA2024 is one of the heat treatable Al-Cu alloys with good strength to weight ratio and fracture resistance. It finds application mainly in aircraft and structural applications. In T351 tempered condition, AA2024 has improved hardness and strength. However, the softness of the matrix leads to high wear rate. In this study, tribological characteristics of AA2024-T351 is determined using a pin-on-disc tribometer by varying the sliding velocity, sliding distance and axial load as per face centered central composite design. A hybrid linear – radial basis function model is developed to explore the effect of normal load, sliding distance and sliding velocity on the wear rate of AA2024-T351 alloy. The predominant wear regimes in AA2024-T351 alloy is understood from the characterization study on the surface morphology of the worn specimens.
