摘要
Primary focus of the current investigation is to analyze the effect of friction stir processing upon AlCoCrCuFe addition on Copper metal-metal surface composites. Copper surface composite along with the prepared novel AlCoCrCuFe high-entropy alloy (HEA) formulated through arc melting technique as reinforcement material is developed in the course following Friction Stir Processing (FSP) technique. Effect of HEA is interested in understanding the microstructural, mechanical and tribological behavior for its 5, 10 and 15 vol% distribution into copper surface. Consequently, fine grain size and hard HEA reinforcement presence upfront the achieved improvement in copper material hardness values. HEA particle additions into base copper matrix viz. fabricated surface composite, originate the following: Strength magnitude is superior than the unprocessed base material; Wear rate lessens towards any addition; Friction coefficient improvises even for minor reinforcement introductions. Among the examined copper surface composite, sample with 15 vol.% addition of HEA has exposed optimistic report (minimal wear; higher strength and hardness) in lieu of this research disclosure.
