Abstract

The interfacial morphology and corrosion resistance of low carbon Fe-B cast steels in zinc bath at 520°C were investigated. The results show Fe-B cast steel containing high Cr and Ni exhibits the best corrosion resistance to liquid zinc. The corrosion layers are composed of Γ-Fe₃Zn₁₀, δ-FeZn₁₀, ξ-FeZn₁₃ and η-Zn. The corrosion behaviour of Fe-B cast steels includes the following processes: the preferential leach and dissolution of Cr and Ni, the formation of Fe-Zn compounds controlled by zinc atom diffusion, and the spalling of borides without the supporting role of α-(Fe,Cr) matrix corroded by liquid zinc.
