| Summary: | In the present study, wear test has been performed on wrought magnesium alloy AZ31 samples. The test samples were in different conditions as; in the as cast alloy or after undergoing different surface treatment of the wrought alloy. The surface treatments included ball burnishing, swaging and shot peening. The shot peening is done at two main pressure loads; 0.1 and 0.3 bars, while other parameters are held constant. The test results show that the wear worst results were observed in the as cast sample at pressure load 0.3 bars, while the shot peening sample has the worst wear rate among all samples at pressure load of 0.1 bars. On the other hand, the hardness test showed that the swaged sample has the highest hardness value among all samples.
