| 摘 要： | The paper concerns with the effects of liquid quality on cavitation erosion, Vari-ous homogeneous liquids such as distilled water, glycerine-water mixtures of different concentra-tion, Kerosene and silicone oil were used as liquid media. Liquids containing solid particles suchas fly-ash ane bakerite powders of different concentration were also studied. Experimental find-ings witnessed the effect of viscosity in attenuating cavitation erosion. Liquids containing solidparticles play dual role of facilitating and alleviating cavitation erosion, in which critical concen-tration and equivalent concentration are in existance. The behaviour of cavitation clouds and theappearance of pittings were also carefully observed to help explain the different effects of liquidquality on cavitation erosion.
