- ItemVyužití kavitace pro zpevňování povrchů(Technická Univerzita v Liberci, 2011) Buďárek, Tomáš; Müller, MilošThis bachelor thesis is focused on the utilization of ultrasonic cavitation for an unconventional hardening of surface layers. The aim of this work is to design an experimental setup utilizing the method of the hardening due to cavitation. The theoretical part discusses the theory of cavitation phenomena, undesirable effects of cavitation and possible use of cavitation. The principles and designs of devices producing cavitation fields are described in detail. Special focus is placed on ultrasonic transducers based on the piezoelectric effect. The hardening effect of cavitation is discussed. The methodology for the testing and the evaluation of hardening due to cavitation are described. Tests of the surface layer hardening are performed for selected materials. The practical part includes a description of the the experiment, a description of the measurement and evaluation results.
