Process: hardening of Axles, using DL028Q, 2.8kW High Power Diode Laser (HPDL)
Industrial sector: Automotive
Material: Any carbon steel or cast iron
Other notes: The surface hardening process relies upon a thermally induced phase change in iron alloys with significant carbon content. The appeal of transformation hardening by laser is the fact that one can direct the laser to harden only the regions desired – leaving the bulk material less brittle. The laser applies far less total heat than other thermal hardening and is almost instant as the part being hardened self-quenches
