The process (mechanism) of erosion of soluble brittle materials caused by cavitation.
This research determines which of the phenomena that appear during cavitation are responsible for the erosion of some brittle water soluble materials, such as gypsum and alum, when exposed to a high intensity ultrasound field over the cavitation level. The observation that gypsum suffers no erosion under the effect of an ultrasound field when the material is irradiated in a saturated solution of gypsum in water initiated the idea of performing this experiment.
