摘要
An experimental test circuit was built with submerged nozzle with diameter 1.2 mm and inlet pressure 200 bar. Several specimens of different cavitation resistant materials used for hydraulic turbines (e.g. 13Cr4Ni) and coatings (e.g. tungsten and chromium carbides) were tested. Cavitating jet tests proved to be very efficient, sufficient cavitation erosion was obtained within 90 minutes. Comparisons between different materials were based on microscopic mapping of the eroded surfaces and SEM visualizations. Finally comparison between cavitating jet test and hydrodynamic cavitation tests using the orifice is presented. Duplex steel weld deposit proved to be the most cavitation resistant material
