Abstract
The immersion test of alicyclic epoxy resin cured with phthalic anhydride was carried out and also the cavitation erosion test was made by using a magnetostriction vibratory apparatus in pure water and NaOH solution. The results were as follows: (1) On the corrosion of epoxy resin, the corrosion depth showed a linear relation with immersion time, and the corrosion rate was increased with increasing concentration of NaOH solution. The resin used in this test showed the surface reaction type corrosion in which resin dissolved from its surface uniformly as a result of hydrolysis reaction. (2) In the case of cavitation erosion behavior, the erosion rate-time curve showed one or two peaks depending on the cavitation intensity such as amplitude of a vibration. The effect of amplitude on the damage was found to be closely associated with the behavior of cavities. (3) In the erosion behavior under the corrosive environment, larger amounts of damage than those in pure erosion or pure corrosion test were caused by the brittle type damage accompanying the generation or acceleration of crack and pit. In conclusion, the interaction between erosion action and corrosion action was clearly recognized.
