Abstract

Depending on the relationships of adhesive and cohesive strengths of gas-dynamic coatings three major versions of plastic flow evolution can be revealed in composition under investigation. Incompatibility of plastic flow evolution in the coating and substrate causes the local bending of specimen which is the major cause of nucleation of the stress concentrator at the interface. The propagation of transverse cohesive crack in the coating as well as adhesive crack along the interface are the result of its relaxation
