FIELD: engines and pumps.
SUBSTANCE: invention relates to a method for epitaxial application of repair material on the surface (38) of the substrate, obtained by directed crystallization. Article is located in fluidized bed (34) for particle drift of repair material over machined surface (38) when rasterizing energy (36) of the laser on the surface for melting of particles and building up of repair material on the entire surface simultaneously. Article is displaced downward (39) in the above layer in direction parallel with orientation of grains in part, with adding material on surface, thus providing continuous epitaxial adding of material on the surface without recrystallization.
EFFECT: invention can be used for repair of articles of gas turbine engine.
