Laser surface hardening is a technology that utilizes a high-energy laser beam to scan the workpiece to harden the surface of the scanned area. The basic principle is to use a certain energy density (103 ~ 105W/cm2) of laser irradiation of the workpiece, so that the irradiated surface area is rapidly heated to the phase transition point above the melting point of the following temperatures, at this time, the workpiece matrix is still in the cold state, the heating zone and the substrate between the existence of a large temperature gradient, when the laser beam stops irradiating, due to the role of heat conduction, the heating zone will be rapidly cooled (106 ~ 108 ℃) / s) and martensitic transformation occurs, so that the surface layer of the workpiece can realize the phase transition hardening.
Laser Output Spot
Diameter 0.2-4mm，10-30mm rectangular light spot
Low thermal effect
Stable heat input, small heat-affected zone, small deformation, effectively improve the fatigue resistance of metal materials.
Non-contact machining, rapid heating and cooling, fast machining speeds, shortened lead times
High processing efficiency
Adopt of flexible optical path selective zone processing, does not affect other areas, thus improving processing efficiency.
Non-destructive and insoluble on surfaces
No damage to the surface of the workpiece after quenching, no need for secondary processing, no cracking on the surface of the mold.
Stabilization is unchanged
Strengthened by matrix self-quenching, no quenching medium, no decarburization of processed parts, no change in material stability, can be quenched repeatedly.
Effectively improve strength
and fatigue resistance
Short thermal cycle time, fine tissue structure, higher lightness and fatigue resistance.
