Factory Supply Laser Hardening/Quenching Machine Laser Heat Treatment Equipment

During the laser heat treatment process, after the laser beam stops scanning, observe the surface state of the laser quenched strip with the naked eye or a low-power magnifying glass at any time, and macroscopically judge the surface quality of the quenched strip. Microscopic analysis should take the cross-sectional area of the quenched strip as the observation surface, and use a metallographic microscope to detect the depth (mm) and width (mm) of the quenched hardening layer at a magnification of 100 times. The depth of laser hardening layer is generally below 1mm. The microstructure of laser quenched steel materials is mainly martensite. The microhardness method should be used to detect the hardness of the quenched layer, and the load value should be selected based on the properties, thickness, and depth of the quenched layer of the sample.
