“…Such studies, besides investigating polymers, composites, and fillers, also investigate hard brittle coatings made of ceramics [93]. On their own, these coatings are resilient to cavitation but, despite some initial success, fail over time [94]. Buravova and Gordopolov [95] observe that pressure loading on the outer surface, albeit of insufficient strength to fracture the surface, i.e.…”

Hard mineral scale fouling results in significant economic losses both industrially and domestically. Recently, attempts have been made to use ultrasound to mitigate scale formation and its removal based on the phenomena of cavitation. Cavitation erosion is the removal of material from a solid surface by pressure shock waves associated with the formation and collapse of bubbles. This paper reviews the literature on cavitation erosion of brittle crystalline materials in an attempt to better understand the relationship between the material properties of CaCO 3 scale deposits and its potential removal by cavitation. The study finds that from a materials perspective cavitation erosion is intimately associated with both a material's bulk properties and importantly to its microstructure. The situation is further complicated because the macro and micro-properties of CaCO 3 scale are dependent on many factors relating to its depositional environment. The type of scale formed will affect how it is removed by cavitation.
