Zusammenfassung:The invention discloses a method for laser-strengthening shaft parts, which is used for improving the performances of the shaft parts used for mechanical equipment and motors and belongs to the technical field of laser cladding. The technical problem to be solved by the invention is to provide the method for laser-strengthening the shaft parts, and the method can improve the performances, retard the abrasion speed and prolong the service life of the shafts. In order to solve the technical problems, the adopted technical scheme comprises the following steps: 1) utilizing the existing method for processing the shaft part, wherein the diameter of the shaft part is reduced by 1.5-1.8mm in comparison with the design value; and 2) mounting the processed shaft part on a chuck of a laser cladding machine, and cladding metal powder on a neck journal, wherein the laser output power is 6.8kw, a laser beam is a 15 multiplied by 2.5 broadband rectangular light spot, the scanning speed is 480-600mm/min, the powder feed rat
