Abstract

The high-quality joining of Al alloys to steel is widely used in automotive manufacturing. However, because of the significant differences in their thermophysical properties, the wetting of Al alloys on steel is very limited, which affects the joining quality. To address this challenge, the laser powder bed fusion (LPBF) technique was used to prepare an FeCoNiCrMn high entropy alloy (HEA) with a dense transition layer (DTL) and micropillar transition layer (MTL) on a steel substrate for the first time. Then, the dynamic wetting and spreading behaviours of Al-12Si alloy over the transition layer-free, DTL, and MTL steels were comparatively studied. The spreading mechanisms were revealed by the spreading dynamics and an analysis of the interfacial microstructure. This study investigated a new method to improve the wetting of Al alloys on steel substrates and elucidated the mechanism of the effect of the HEA transition layer formed using LPBF on Al/steel wetting, which may provide some guidance for improving brazing, welding, coating, and other processes involving solid/liquid interfacial interactions.

激光粉末床熔合高熵合金过渡层对铝合金在钢基体表面润湿扩散行为的影响

铝合金与钢的高质量连接在汽车制造中有着广泛的应用。然而，由于两者热物理性能的显著差异，铝合金对钢的润湿作用非常有限，影响了连接质量。为了解决这一挑战，首次采用激光粉末床熔合（LPBF）技术在钢基体上制备了具有致密过渡层（DTL）和微柱过渡层（MTL）的FeCoNiCrMn高熵合金（HEA）。然后，比较研究了Al-12Si合金在无过渡层钢、DTL钢和MTL钢上的动态润湿和扩散行为。通过扩散动力学和界面微观结构分析揭示了扩散机理。本研究探索了一种改善铝合金在钢基体上润湿性的新方法，并阐明了LPBF形成的HEA过渡层对铝/钢润湿性影响的机理，为改善钎焊、焊接、涂层等涉及固/液界面相互作用的工艺提供了一定的指导。
