abstract The usage of ceramic materials in applications endangered by intensive cavitation could limit erosion phenome-na. Especially effective improvement could be achieved with the application of sintered ceramic matrix compo-sites (CMC). The presented work describes the cavitation wear resistance of a few CMCs in comparison to mo-no-phase ceramic sinters made of alumina and tetragonal zirconia. Their degradation was described by the volumetric loss of material. Additionally, the cavitation degradation mechanisms of each particular material were determined by detailed observations of worn surfaces at different stages of wear.
