TAccording to the working condition and failure forms of converter flue, in order to improve the service life of the flue, 3 layer composite coatings with mainly composed of Ni-Cr alloy by supersonic arc spraying were designed. Metallographic observation, micro hardness analysis, high temperature oxidation test and thermal shock resistance test for the coating showed that the composite coating has high binding strength with the substrate and excellent wear and corrosion resistance.
