Abstract

The objective of this work was to construct a prototype for cavitation test and use it to analyses the damage created by the cavitation phenomenon on a test piece. Throughout this work, a prototype was proposed, assembled and adjusted in order to allow evaluate the effects of cavitation in hydraulic (water) medium. This prototype was used both to test small samples of engineering materials, focusing on metals, and to obtain parameters for the construction of the final test equipment. Comparing the results before and after the cavitation tests, became possible a discussion and quan-tification of cavitation impact on the material integrity as well its performance on usage.
