摘要	To improve the microstructure and properties of high-aluminum bronze coatings prepared by supersonic plasma spraying, the coatings were remelted with a high-frequency induction system. The microstructure characteristics and interface bonding state of the coatings were studied by metallurgical microscopy, scanning electron microscopy, X-ray diffraction, energy dispersion analysis, porosity measurement, microhardness testing and mechanical strength testing. It is indicated that laminar structure characteristics and a small amount of oxidation slag, pores and incompletely melted particles exist in the coating before remelting. Mechanical combination is the main way to join the matrix and the coating. Incompletely melted particles and laminar structure characteristics are lessened in the coating after remelting. The porosity of the coating after remelting is lower than before remelting. A white metallurgical band forms in the interface because of element diffusion between the matrix and the coating, which would enhance the adhesion. A higher hardness is observed in both the diffusion zone and the surface of the remelting coating, and the interfacial bonding strength increases from 25.110 before remelting to 83.358 MPa after remelting.
