    摘要: In one embodiment, a laser peening apparatus includes an output unit (41) configured to output laser light (6); a light-guide unit (31) configured to guide the outputted laser light (6); a condenser lens (42) configured to condense the guided laser light (6) ; an irradiation nozzle (32) configured to radiate the condensed laser light (6) ; a focus-change unit (50) configured to change a focal position of the laser light (6) based on distance from an irradiation target (4, 5) of the laser light (6) to the irradiation nozzle (32); and a control unit (66) configured to apply laser peening by radiating the laser light (6) toward the irradiation target (4, 5) which is in contact with water.

    摘要: The method involves subjecting at least a portion of the part to a first step that involves moving at least one laser beam in at least one pass over said portion, until partial or total transformation of the surface layer of the portion in question and modification of the concentration distribution of nitrogen in the diffusion area, and subjecting at least the portion treated by laser to transform the surface layer, to a second step that involves moving at least one laser beam in at least one pass over said portion in order to reduce the nitrogen concentration in the underlying diffusion layer.
