In order to investigate the simultaneous attack behavior of erosion and corrosion of alicyclic epoxy resin, cavitation erosion tests were made by using a magnetostiction vibratory apparatus in pure water and NaOH solution. The results obtained were as follows: (1) By promoting crack initiation and growth, the erosion damage was accelerated by corrosion. (2) By enlarging surface area and removing corrosive products, the corrosion damage was promoted by erosion. (3) It was also found that the synergistic effect in cavitation erosioncorrosion markedly depended on the relative intensity of cavitation erosion to the concentration of corrosive liquids. (4) Based on the theory of crack propagation, an equation for predicting the damage loss was proposed.
