文摘This paper is mainly devoted to conduct a series of vibratory cavitation erosion tests using the magnetostriction apparatus. Distilled water was used as a standard liquid medium for comparison and other liquids were glycerine, kerosene, silicone oil and water containing different concentration glycerine and solid particles, bakerite and fly ash. Experimental results indicate that viscosity of liquid restrains, attenuates and alleviats cavitation erosion. Experiments witness that there exists critical concentration and equivalent concentration. The behaviour of cavitation clouds and the appearance of the pitting were observed. It is helpful to explain the effect of liquid quality on cavitation erosion.
