英文摘要	In order to investigate the coating preparation ability and the characteristics of the coating of the high-aluminium copper coarse powders prepared by supersonic plasma spraying and induction-refusion composite technology, the coating was prefabricated by supersonic plasma spraying, and the coating was remelted by a high frequency induction system. Furthermore, the microstructure characteristics and the combination state of the interface were investigated on the coating. The results show that the high-aluminium copper coarse powder coating prepared by supersonic plasma spraying is heavily oxidated. In particular, a good deal of oxide is focused on the interface, which makes the coating ineffectively bond with the substrate, and the abundant oxides and holes segregate laminar flow layer, blocking them from sintering. At the same time, the coating has significant element segregation. However, using the induction remelting technology, the coating has even smaller organization, a mass of oxide is expelled, and the coating bonds with substrate by means of metallurgy. Concurrently, induction-refusion homogenizes the coating elements. This investigation demonstrates that the supersonic plasma spraying and induction-refusion composite technology has the ability to prepare a high-aluminium copper alloy coating with coarse powders. A metallurgical belt with a width of 10 to 15 μm is formed in the interface of the coating and the substrate.
