Wettability of Mg and AZ91 Alloy on Ti6Al4V Alloy Substrate

The wettability of liquid Mg and AZ91 alloy on bulk Ti6Al4V alloy was investigated in the current study. Wetting experiments were conducted by gradually heating the samples to 800°C for 30 minutes. A CCD camera was used to capture the morphological changes in the droplet during contact angle measurements. Additionally, a scanning electron microscope (SEM) equipped with energy-dispersive X ray spectroscopy (EDS) was used to analyze the morphology and microstructure of the wetted surfaces of the Ti6Al4V alloy. X-ray diffraction analysis (XRD) was performed so as to examine the phase constituents in the reaction layer of the Ti-alloy substrate and magnesium and AZ91 alloy.
