An Experimental Study on the Cavitation-erosion Behavior of Journal Bearings

An experimental device for evaluating the cavitation erosion behavior of journal bearings was established based on the principle of ultrasonic vibration. The cavitation erosion behavior of a journal bearing was experimentally investigated with the device. Some new phenomena of cavitation erosion were observed, while the cavitation erosion mechanisms of the journal bearing was discussed and analyzed, by summarizing many experimental phenomena and results.
