Abstract: The paper deals with the studies on the reconstruction and innovation of ordinary magnetostriction apparatus for cavitation erosion tests of non-metallic materials. It aims at making testing specimen to be independent with amplitude amplifier rod each other, thus solving the problem of difficulties to fix tightly the non-metallic specimen to the vibrating rod. Such approach makes the exposure area greatly increased and effectively mitigates the effect on the testing result due to non-homogeneity of nonmetallic specimen, thus extending the application of magnetostriction apparatus to carry out cavitation erosion tests to larger size of non-metallic and non-homogeneous materials. It will render a set of new innovative apparatus and recently developed method to conduct fast and simple cavitation erosion test to be carried out in days to come. Simultaneously several non-metallic materials have been made by means of such new apparatus yielding satisfactory results and witnessing the availability of new method.
