To avoid flow surface morphology change caused by wear and cavitation erosion of turbine movable guide vane and the unit efficiency decrease, ultrasonic vibration cavitation machine, high-speed jet of gaza's grinding apparatus and circle grinding apparatus were used to carry out cavitation erosion test for epoxy mortar, mortar composite resin and polyurethane and movable guide vane base material of #45 steel. Based on the test results, the cavitation erosion resistance and impact wear resistance of different materials were analyzed, and the service life of materials under strong cavitation erosion was predicted. The influence of flow rate, attack angle and sand content on material wear was studied, and the prediction model of material wear was established. The results show that the corrosion resistance of the materials is as follows: polyurethane > composite resin mortar > epoxy mortar; The abrasion loss of material has a linear or exponential relationship with the increase of velocity. The relationship between wear and sand content is linear. When the attack angle increases gradually, the impact wear first reaches the peak value and then decreases gradually. The critical attack angle of different materials is different.
