英文摘要The cavitation erosion experiments of 316LN SS in 3.5 wt% NaCl solution were done using an ultrasonic vibrator. The weight loss, surface roughness and surface morphology of 316LN SS at different cavitation erosion stages were analyzed by an analytical balance, roughness profiler, 3D video microscope and SEM. The cavitation erosion mechanism of 316LN SS was briefly discussed through the electrochemical testings when cavitation existed or not. In the cavitation erosion process of 316LN SS, the surface roughness increased linearly and then slowed down, but the cumulative weight loss and the mean corrosion depth hardly changed at initial stage and increased greatly hereafter. Under the continuous action of vacuolar collapse, grain boundaries of 316LN SS were preferentially dissolved, the pitting was simultaneously formed and then obvious peeling pits and cracks were finally present on the sample surface. Comparing to the static solutions, the corrosion current density of 316LN SS in cavitation environments was bigger, and the passive zone was also narrower. That was to say, the cavitation erosion of 316LN SS was the synergetic effect process of cavitation mechanics and electrochemical corrosion. The cavitation effect promoted the occurrence of electrochemical corrosion, and the electrochemical corrosion further enhanced the role of cavitation mechanics.
