摘要
This paper deals with the reconstruction and innovation of an ordinary magnetostriction apparatus for cavitation erosion tests of non metallic materials. It aims at making testing specimen to be independent of amplitude amplifier rod, thus overcoming the difficulties of fixing tightly the non metallic specimen to the vibrating rod. Such approach makes the exposure area greatly increased and effectively mitigates the effect of non homogeneity of non metallic specimen on the testing results, 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 in days to come. Simultaneously, several tests on non metallic materials have been made by means of such new apparatus, yielding satisfactory results and witnessing the availability of new methods.
