Abstract

In this study, the ZnFe coated boron steel specimens were treated by rapid heating at different heating rates from 20 ℃/s to 100 ℃/s. The coating morphologies and phase compositions were characterized to investigate the influence of heating rate on phase transformation of ZnFe coating. The results indicated that there was no continuous α-Fe(Zn) layer formed at coating/substrate interface during the heating-up stage when the heating rate was higher than 50 ℃/s. As a result, the phase transformation of the coating was facilitated. At the heating rate of 100 ℃/s, a one-layer coating structure composed of α-Fe(Zn) phase was formed within 100 s, which is significantly shortened compared to the traditional furnace heating method.
