Kavitations-Korrosion,Schadensbilder und Mechanismen – Vergleich zwischen Strömungskavitation,Kavitation durch rotierende gelochte Scheibe und Schwingungskavitation

Cavitation corrosion, damage phenomenology and mechanisms–comparisons between flow cavitation corrosion, cavitation by rotating perforated disc and vibration cavitation In a joint test programme involving different cavitation test devices (vibrator, rotating disc, flow channel) the influence of imploding cavitation bubbles on aluminium was investigated. The behaviour of the material was described in terms of macroscopical (mass loss-testing time and similar curves) and microscopical (investigations by SEM) methods. Lots of similarities in the kinetic of destruction and in the appearance of the damaged material could be found.
