Cavitation damage is affected by physical properties of liquid. In order to study such an effect solely caused by the change of surface tension, cavitation erosion tests were performed using waters with different surface tensions. The value of surface tension was adjusted by adding photographic wetting agent, ranging from 0.0025 to 3.0% (wt.%). The mechanism of surface tension influence on cavitation damage is discussed by relating it to the observed cavitation pattern and bubble behavior. The erosion rate firstly decreases gradually and then drops sharply at about half the value for water (sigma=30 x 10(-3) N/m) when surface tension reduces from that of water. It was also observed that due to the addition of wetting agent, both the maximum of pulse peak height and the num
