Abstract: Provided are a method and an apparatus for laser quenching. The method utilizes a scanning galvanometer, and involves laser quenching via irradiation with intermittent, repeated scans, rather than a single scan as in the prior art. The method results in increased laser energy absorbed by the metal base and improved depth of thermal conduction, while avoiding melting at the metal surface, thus providing a significantly improved laser quenching process. The apparatus can include a laser, a control system, a light guiding system, a mechanical motion device and a galvanometer.

Abstract: Provided are a method and an apparatus for laser quenching. The method takes the advantage of a high jumping speed of a scanning galvanometer, and adopts the method of heating on multiple or even high frequency repeated scans instead of on a single scan in prior art for laser quenching, wherein the laser energy is fed into the surface of a workpiece by way of short time and multiple superimposed heating, cumulatively, the laser energy absorbed by the metal base is increased and the depth of thermal conduction is improved also. The apparatus includes a laser, a control system, a light guiding system, a mechanical motion device and a scanning galvanometer. Therefore, even though the used laser power is relative high, the surface temperature of a metal object can be always restricted below its melting point and the heat can be conducted from the surface to the internal of a workpiece by thermal conduction constantly and effectively as a result of high scanning speed and the introduce of time interval at scanning, so that melting in the metal surface can be avoided, and the depth of the austenitizing region in the surface of the workpiece and the productivity of laser quenching can be significantly improved.
