FIELD: machine building.SUBSTANCE: laser impacts are applied so that ridges are created along perimetre of application zones of those laser impacts. Ridges form relief elements being swirlers. Marks after application of laser impact have square, rectangular, round or elliptical shape. Laser impacts are arranged so that marks of implemented laser impacts are adjacent to each other or cover each other partially.EFFECT: invention allows increasing strength of machined part, as well as providing the possibility of action on boundary layer.6 cl, 7 dwg |
