Abstract
FIELD: machine industry for applying protective coatings onto parts and tools. SUBSTANCE: method comprises steps of preliminary preparation of a surface of a vane end, gasothermic deposition of a coating and fusion by a laser irradiation in such a way that fusion of edge zones is performed upon a power density, consisting 0.33-0.41 of a power density used for fusion of an end central part; setting duration of the edge zones equal to 0.15-0.27 of a piece of a straight line, connecting terminals of the vane end. EFFECT: enhanced quality of restored vanes due to elimination of deformation of edge zones of the vane end. 1 tbl
