    Abstract:
    The paper presents research results regarding the behavior at cavitation erosion of the CuAl10.5Ni5Fe4.8Mn1.5 bronze used in manufacturing ship propelers. For the experimental research it was used the Standard Vibratory Apparatus with piezoelectric crystals, of the Timisoara Polytechnic University Cavitation Laboratory. The analyze is realized by using the curves and parameters recommended in the ASTM G32-2010 Standard, the photographic images and the profiles of the surface subjected to cavitation. The resistance evaluation was obtained by comparisons with the behavior of the stainless steel OH12NDL for which we have numerous laboratory researches as well as detailed informations about the behavior in field running. The final conclusion is that the researched bronze has a very good cavitation erosion and can be used for manufacturing ship propellers.
