Abstract: The research progresses of various remelting techniques to improve the quality of thermal spraying coatings in recent years were summarized. The following conclusions are obtained:  laser remelting may obviously improve the quality of coatings by eliminating microcracks and unmelted particles in coatings, induction remelting may significantly reduce the porosity of coatings and enhance the mechanics properties of the coatings, and tungsten argon arc remelting can effectively improve the wear and corrosion resistance of coatings and improve the comprehensive properties of coatings. Electron beam remelting and flame remelting also improve the microstructure, microhardness and interfacial bonding strength of the coatings. Finally, the advantages and disadvantages of different remelting technologies were compared, and the development prospects of remelting technology were prospected.

Key words:  , thermal spraying coating, remelting, wear resistance, corrosion resistance
