Abstract

Cavitation erosion was studied for pure tianium (TB270H, TB340H, TP49H) and stainless steel (SUS316L) samples using a rotating disk apparatus in seawater and tap water. In addition, identical experiments for titanium alloy (Ti-6Al-V, Ti-15V-3Cr-3Cn-3Al) samples were carried out in salt water (3%) and ion exchange water using a vibratory apparatus. Erosion resistance of pure titanium in seawater is excellent, as it is in tap water, but the incubation period in seawater is shorter than that in tap water. Erosion resistance of stainless steel is excellent in tap water, but it is necessary to advance the time for its inspection when stainless steel is used for the seawater pump impeller material because the resistance decreases remarkably in seawater. Normalized erosion resistance of these metals using a rotating disk and a vibratory apparatus can be evaluated similarly in terms of Vickers hardness (HV) when it is arranged using a standard material.
