FIELD: machine building.
SUBSTANCE: invention relates to the method for reinforcing the front edge (16) of the blade (12) to protect thereof and to the blade reinforced. The reinforcement is performed by applying a metallic coating (32) on the front edge (16) by thermal spraying of reinforcing material (30) under pressure . Before the step of thermal spraying under pressure in the blade (12) on both sides of the front edge (16) there are at least one longitudinal groove (41, 43) to define. The reinforcing material is applied to the said grooves (41, 43).
EFFECT: invention may be applied in the manufacture or repair of turbine engine blades, helicopter or propeller.
