Abstract

In this study, a multi-step rapid heating procedure composed of two holding stages is developed to achieve fast alloying as well as less zinc loss of the zinc coating. The oxidation behavior during the first holding stage and the microstructure evolution during the final holding stage of the zinc coating are investigated. The results suggest that a continuous surface oxidation layer can be formed during the first dwell stage. In addition, the phase structures of the zinc-based coating treated by multi-step rapid heating show dramatic difference compared with that of the coating subjected to direct rapid heating. Furthermore, the zinc loss due to evaporation could be reduced by the multi-step rapid heating procedure.
