The interface erosion–wear behaviors of Fe–B alloy with different Fe2B orientations in flowing zinc at 460 °C were studied. The results revealed that, for a rotation speed of 100 rpm, the directional Fe–B alloy with a “Fe2B⊥interface” structure (the [002] orientation of Fe2B) exhibits the best erosion–wear resistance. Moreover, the relationship between the Fe2B orientation and ferrite matrix had a significant effect on the erosion–wear microdamage mechanism. Parallel Fe2B zinc suppressive layers were formed at the “Fe2B⊥interface”, thereby preventing erosion of the matrix by the liquid zinc. Furthermore, Fe–Zn products such as δ-FeZn10 and ζ-FeZn13 formed near the liquid zinc. During the damage process, the directional Fe2B and ferrite matrix structure exhibited a good protective and supporting effect, which combined to reduce the weight loss associated with the damage.

Fe2B取向形态对Fe-B合金在锌液中高温冲蚀磨损行为的影响

研究了不同Fe 2 B 取向的Fe-B 合金在460 °C 流动锌中的界面冲蚀磨损行为。结果表明,当转速为 100 rpm 时,具有“Fe 2 B⊥界面”结构(Fe 2 B的 [002] 取向)的定向 Fe-B 合金表现出最好的耐冲蚀磨损性能。此外,Fe 2 B 取向和铁素体基体之间的关系对冲蚀磨损微损伤机制有显着影响。在“Fe 2 B”处形成平行的 Fe 2 B 锌抑制层B⊥界面”,从而防止锌液对基体的侵蚀。此外,在液态锌附近形成了 Fe-Zn 产物,如 δ-FeZn10 和 ζ-FeZn13。在损伤过程中,定向的Fe 2 B和铁氧体基体结构表现出良好的保护和支撑作用,结合起来减少了与损伤相关的重量损失。
