Laser heat treating (laser heat treating) is abbreviated as LHT, also known as laser quenching or laser phase transformation hardening. It scans the workpiece quickly with a high-energy laser beam, so that the surface temperature of the irradiated metal or alloy rises above the phase transition point at an extremely fast speed. When the laser beam leaves the irradiated part, due to heat conduction, the matrix in a cold state makes Rapid cooling and self-cooling quenching to obtain a surface heat treatment method with a finer hardened layer structure.
