论文摘要
Zn-Fe coatings on Q235 steel are prepared by pack cementation process at 390 ℃ for 2,4,6,8 and10 h to investigate the effects of the deposition time on the thickness and corrosion behavior of the Zn-Fe coatings.The thickness of the coating increases with the increase of the deposition time.The coating is composed of a thick outer layer and a thin inner layer.The formation of the coating depends on the inward diffusion of Zn atoms and the outward diffusion of Fe atoms.The outer layer is composed of Fe11 Zn40 and FeZn10 phases.The corrosion behavior of the Zn-Fe coatings is evaluated by immersion test and polarization test.The results show that the Zn-Fe coatings can effectively prevent the Q235 steel from corrosion.The corrosion resistance of the coating is proportional to the deposition time.
