The paper presents the multi-criteria optimization results of heat-resistant coatings detonation spraying technology. The following criteria for optimization of detonation spraying technology are chosen: critical deformation of coating fracture, adhesion-cohesion equal strength of coating and specific technological cost of coating application. Dependences of the strength properties values of the studied detonation coatings at change of technological and constructive factors have been obtained. It is proved that the greatest influence on the mechanical properties of the studied detonation coatings is exerted by the material of the hardened part and the material composition of the sprayed coating, which is caused by the difference in their thermophysical, chemical and mechanical properties, as well as by the physical and chemical processes occurring during the formation of the sprayed layer. The optimum technological parameters allowing to obtain coatings with specified mechanical properties have been established.
