Descriptions
Cavitation erosion was studied for various pure titanium and titanium alloy samples using the cavitating liquid jet method in seawater, the erosion rate of which is more than five times that of the rotating disc method. For that reason, their respective erosion resistances were evaluated in terms of Vickers hardness (HV). The resistance increased in order of increasing hardness : pure titanium samples of first, second, and third types, and titanium alloy (Ti -6Al -4V), as well as in cases using vibratory and rotating disk apparatuses.
