Surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material’s surface, forming a thin layer of a harder alloy. Selective hardening processes can be done by flame, induction, electron beams and laser beam. Flame hardening is widely used in deep hardening for large substrates. Induction hardening is suitable for small parts in production lines. Electron beam and laser beam hardening are sometimes not distinguished from in from those in hard facings or high-energy treatments. These processes are applicable only to steels that have sufficient carbon and alloy content to allow quench hardening. Diode laser can be used to harden the material in localized area, so that only the stress zones of a part can be harden.
