Abstract : In this study, friction stir processing was applied on AA5083, with an objective to improve its wear resistance. FSP was conducted by varying tool rotation speed, tool traverse speed and tool shoulder diameter as per face centered central composite design. Adhesive wear test was performed using a pin-on-disc tribometer. The test results indicate that the wear resistance of most of the friction stir processed specimens was higher than the base material. A mathematical model was generated for predicting the wear resistance using linear-radial basis function and it was used to explore the influence of process parameters on the wear resistance. © 2017 Elsevier Ltd.
