Laser heat treatment is a surface heat treatment technique. That is, the surface heat treatment is realized by heating the surface of the metal material with a laser. Laser heating has an extremely high power density, that is, a very high power is concentrated per unit area of ​​the irradiation area of ​​the laser. Laser heat treatment is a surface heat treatment technique. That is, the surface heat treatment is realized by heating the surface of the metal material with a laser. Laser heating has an extremely high power density, that is, a very high power is concentrated per unit area of ​​the irradiation area of ​​the laser. Due to the extremely high power density, the heat conduction of the workpiece cannot transfer heat away in time. As a result, the workpiece is rapidly heated by the laser irradiation zone to the austenitizing temperature for rapid heating. When the laser heating is finished, since the temperature of the workpiece substrate is kept at a low temperature during rapid heating, the heated region can be rapidly cooled by the heat conduction of the workpiece itself, thereby achieving heat treatment effects such as quenching. Laser quenching effect: Hardness distribution curve of laser quenching layer Hardness distribution of laser quenching layer Laser quenching technology can surface various rails, large gears, journals, cylinder inner walls, molds, dampers, friction wheels, rolls, roller parts strengthen. Suitable materials are medium and high carbon steel and cast iron. Application examples of laser quenching: laser quenching and strengthening cast iron engine cylinders, the hardness of HB230 is increased to HB680, and the service life is increased by 2~3 times.
