Criteria for the Selection of Coatings in the Cavitation Wear

In this work brand new conceptual approach is offered for creation of the cavitationstable coverages, which bases on the development of the criteria of choice coverages and technology of the r receipt. Physical ctiterial choice of protective materials is based on the analysis of waves processes that take place at distribution of shock waves duting the cavitation. The materials criteria of optimization the structure and composition are based on principles of theory of wear and allow to estimate firmness of coverages in the conditions of the cavitation, taking into account their mechanical descriptions is hardness and cracking.
