Investigation on Ultrasonic Cavitation Erosion of Aluminum–Titanium Alloys in Sodium Chloride Solution

Two kinds of Ti-alloys, i.e., Al–5Ti and Al–10Ti alloys, were manufactured in this study, and their ultrasonic cavitation erosion behaviors in 3.5 wt.% NaCl solution were evaluated by the cumulative mass loss, scanning electronic micrograph, and three-dimensional morphology. The results show that ma...
