Liquid is the medium that causes cavitation wear. It does not require a second surface; it requires only that high relative motion between the surface and liquid causing low pressure areas in the liquid. These low pressure areas create voids that collapse or implode near the metal surface causing severe wear. Cavitation wear usually occurs in applications such as Pumps & Valves, Hydro power etc.
Cobalt based material having high toughness deposited through HP-HVOF process having good adhesion with base material will provide good resistance to cavitation wear. Few coatings suggested by us for applications involving Cavitation Wear are :
