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.

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。
