Wear Mitigation in Cast Magnesium Alloy through Flyash Reinforced Friction Stir Surface Compositing

Abstract:

An attempt is made to mitigate wear in cast magnesium alloy by incorporating flyash reinforcement on the surface through friction stir processing. Wear resistance is evaluated using pin-on-disc wear testing. Effect of dry sliding wear process parameters such as speed, time and distance were studied by using design of experiments. Empirical relationships were established between the process parameters and wear resistance of base metal as well as surface composite. Further, wear map is constructed using graphical optimization technique, which can be used to predict the lower and upper bound of wear rate for the both base metal and friction stir processed surface composites under dry sliding condition.
