Laser hardening is a heat treatment process or surface hardening process in which a laser beam is used to heat the surface of a metal part.
This modern technique of hardening is predominantly for strengthen used on materials and components that are prone to wear.
This process is used exclusively on ferrous materials suitable for hardening, including steels and cast iron with a carbon content of more than 0.2 percent.

Laser hardening consists of the rapid heating of a material’s surface by laser beam, the energy from the laser beam is applied directly to the component surface. The surface layer is heated up to the hardening temperature (>1000°C) in a reduced area within a very short period of time, a short hold at the target temperature, and intensive cooling due to the high thermal conductivity of the material. During the cool-down period a process called "self-quenching" takes place, where a fine-grained structure is formed in the thin layer on the surface of the part. This results in a significant increase in hardness of metal part.
The hardening depth of the outer layer is normally 0.1 to 1.5 millimeters, although on some materials, it may be 2.5 millimeters or more.
Lasers tend to produce harder surfaces to a shallower depth compared to other hardening processes. This makes laser hardening ideal for improving the performance of intricate and high accuracy components.
This differs from conventional methods, which are less precise and more invasive to your materials.
