Abstract
The wetting behavior and the interfacial characterization of Ti32.8Zr30.2Cu9Ni5.3Be22.7 (denoted as ZT3) bulk metallic glass (BMG) alloy and Ti55 substrate were investigated by the sessile drop method at 1023–1223K in a high vacuum. We found that the system had the final equilibrium contact angle around 40°, 27°, 24°, 20° and 18° at the corresponding experimental temperatures. During the experiment, elements in the substrate diffused upward and formed an interfacial layer at the interface, and then the dendritic phase formed in the cooling process. The thickness of the interfacial layer and the height of the dendrite increased with the increasing experimental temperature. Ti and Zr elements are the main components of the interfacial layer. XRD and EDS results show that the compositions of the interface layer are β-Ti (Zr, Cu, Al), which is different from that of droplet and substrate.
