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.

当前研究的主要重点是分析在铜金属-金属表面复合材料上添加AlCoCrCuFe的摩擦搅拌过程的影响。在搅拌摩擦加工（FSP）技术的过程中，开发了铜表面复合材料以及通过电弧熔化技术配制的新型AlCoCrCuFe高熵合金（HEA）作为增强材料。HEA的作用有兴趣了解其在铜表面的5、10和15％（体积）分布的微观结构，力学和摩擦学行为。因此，晶粒细小和坚硬的HEA增强材料可以预先实现铜材料硬度值的改善。HEA颗粒添加到基础铜基质中。人造表面复合材料，产生以下原因：强度等级优于未加工的基材；磨损率随添加而减少；即使是少量的钢筋引入，摩擦系数也可以改善。在所检查的铜表面复合材料中，代替本研究公开内容的样品，添加15％（体积）的HEA暴露出乐观的报告（最小磨损；更高的强度和硬度）。
