The behavior of the material under cavitation and abrasive wear is considered. An analysis of easily determined wear resistance criteria is given. It has been shown that the resistance of metals to fracture under micro-impact loading is determined not by ordinary mechanical characteristics, but by the strength of individual micro-sections or structural components. And with cavitation erosion, corrosion makes a significant contribution, which is not taken into account when determining mechanical characteristics. The prospects for assessing the erosion resistance of materials using energy criteria are shown, since their specific values depend on factors characterizing the system that is under external influence: the stress state pattern of the wear layers, the deformation rate, the micro-and submicrostructure of the deformed volumes, as well as the cyclic of the external loading.
