A systematic investigation has been carried out on cavitation erosion in solid-water mixtures using vibratory test facilities and some analytical devices. A mixture of distilled water and heterogeneous solid particles is used. It is shown in this work that solid particles play significant roles on acoustic cavitation erosion through two ways when present in liquids. They, aggravate the abrasive wear of materials owing to the effects of particle size, concentration, and hardness. In addition, they relieve the damage produced by the reduction of the collapse pressure of cavitation bubble because of the variation of the physical properties in mixtures. Total erosion is dependent on this governing factor.
