Abstract
The effect of Fe2B orientation in Fe-3.5 wt.% B steel on its erosion-corrosion behavior in 460 °C flowing zinc was investigated. The results indicate that the erosion-corrosion resistance of Fe-3.5 wt.% B steel relies strongly on Fe2B orientation. The orientation of Fe2B determines the erosion-corrosion interface, which governs the diffusion, interfacial reaction, failure mode of Fe2B, and significantly influences the erosion-corrosion behavior. The strong pinning effect of corrosion products and columnar Fe2B suppresses erosion-corrosion; this suppression results in good erosion-corrosion resistance to liquid zinc of the Fe-3.5 wt.% B steel with the [0 0 2] direction of Fe2B perpendicular to the erosion-corrosion interface.
