Laser quenching machine is a surface strengthening equipment that uses high-energy density laser beams (10 ³ -10 ⁵ W/cm ²) to rapidly heat and self quench the metal surface. The core is to instantly austenitize the surface layer (0.1-2 mm), and then form high hardness martensite through self cooling of the substrate, improving wear resistance and fatigue life while maintaining toughness of the substrate.
Working principle
Rapid heating: Laser focuses on the workpiece, causing the surface to rise in milliseconds to 850-950 ℃ (austenitization), with heat concentrated only on the surface and the substrate in a cold state.
Self cooling quenching: After the laser is removed, the surface is rapidly cooled at 10 ⁴ -10 ⁶ ℃/s, transforming austenite into martensite and achieving self cooling quenching without the need for water/oil media.
Strengthening effect: The hardened layer is uniform, the grain size is fine, the hardness is 1-3 HRC higher than traditional quenching, and the wear resistance is increased by 1-10 times.
