The microstructure of the surface of samples obtained from refractories, which were selected from four characteristic zones of heating cages of coke oven batteries of the Avdeevka Coke Plant, was investigated. The result of the work is a prepared experimental installation and samples for the application of coatings; the characteristic particle size for closing cavities and pores is established; The range of the distance of the edge of the Laval nozzle relative to the working surface of the specimen is established at which adhesion of particles sprayed with the surface layer of the refractory is ensured; The maximum particle size is established provided that the velocity of the particle is above the critical velocity; Separate particles were applied to the surface at the base parameters of the installation; preliminary studies of the microstructure of the samples were carried out.
