英文摘要	The Cu-added Ni60/Cu directional structure composite Coating was prepared by flame spraying+induction remelting+forced cooling composite technology. The effects of Cu content on the microstructure, phase evolution, microhardness and friction and wear properties of Ni60/Cu oriented structure coating were studied. The results show that the Cu element diffuses continuously into the grain during the formation of the directional structure coating, resulting in a continuous decrease in the hardness of the coating as the Cu content increases. The content of Cu has an important influence on the microstructure of the coating. When the Cu content is 15%, the directional structure of the coating shows a growth characteristic perpendicular to the interface, and the microstructure is fine and regular. The coating is mainly abrasive wear, which shows the lowest friction coefficient and the lowest wear rate, and gives full play to the friction reducing effect caused by Cu element when the Cu content is 15%. However, the excessive addition of Cu makes the wear resistance of the coating worse.
