Abstract
The present research pacts with fabrication of Cu – HEA surface MMC through solid state Friction Stir process (FSP) and analysis of wear characteristics. AlCoCrCuFe HEA with higher hardness values vacillated up in the level of 770HV is selected as reinforcement. The wear test is performed for 16 parameter combinations based on Taguchi method with the aid of Pin-on-Disc apparatus. The input parameters considered are HEA percentage, applied load, sliding velocity and distance whereas wear rate and coeffi cient of friction are chosen as response. WR signifi cantly decreases with HEA additions and increases with increase in load, sliding velocity and sliding distance. The consequence of HEA addition on CoF during dry sliding wear test is contradictory to its effect over WR. ANOVA results confi rmed the signifi cant effect of reinforced HEA over wear characteristics of copper composite. TOPSIS methodology is followed to fi nd the best possible parameter combination that yields better wear rate and coeffi cient of friction.
