AbstractThe wetting behavior and the interfacial characteristics of the molten Bi-Sn on the AlCoFeNiCr HEA (high entropy alloy) and the CuCoFeNiCr HEA substrate were investigated by a sessile drop method. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS) were used to analyze the microstructure of the Bi-Sn/AlCoFeNiCr HEA and Bi-Sn/CuCoFeNiCr HEA interface. The results show that the AlCoFeNiCr HEA and the CuCoFeNiCr HEA form with a single solid solution structure. However, Bi-Sn molten alloy on CuCoFeNiCr HEA substrate has better wetting characteristics than Bi-Sn molten alloy on AlCoFeNiCr HEA substrate. With increasing wetting temperature, a number of intermetallic compounds are generated at the interface between the molten Bi-Sn and the CuCoFeNiCr HEA substrate, and the diffusion of Sn atom along the Cu-rich solid-solution phase in CuCoFeNiCr HEA is much more intense. On the contrary, the interface of the Bi-Sn/AlCoFeNiCr HEA system is still the straight interface, and there are new intermetallic compounds on the Bi-Sn/AlCoFeNiCr HEA interface with increasing wetting temperature. It is found that the Cu-rich phase in CuCoFeNiCr HEA provides a "wetting channel" for the wetting process between the molten Bi-Sn and CuCoFeNiCr HEA substrate, which result in the two wetting systems with different wetting mechanisms.
