Laser Quenching
High processing efficiency: The material surface is rapidly heated and rapidly cools down by itself, which is conducive to increasing the scanning speed and corresponding productivity, potentially replacing traditional quenching.
Controllable quenching quality: Laser phase transformation hardening usually results in a hardness that is 5-20% higher than conventional phase transformation hardening, achieving an extremely fine hardened layer structure. By using high-power lasers, the depth of the hardened layer can reach up to 2mm.
Minimal processing deformation: Due to the rapid heating speed of the laser, the heat-affected zone is small, resulting in minimal phase transformation hardening stress and deformation.
Quenching area optional: It can be used to harden parts with complex shapes and parts that cannot be processed by other conventional methods, such as parts with grooves.
High degree of automation: The process is easy to achieve computer control and has a high degree of automation, which can be incorporated into the production line.
Non polluting to the environment: The heat generated by laser phase change hardening is self cooled through conduction from the surface to the inside, without the need for cooling media such as water and oil, or the addition of functional alloy materials, which is environmentally friendly and energy-saving.
