Technology - Laser Hardening
| The surface hardening with high power diode laser (short laser hardening and laser-beam hardening) is increasingly used in industrial manufacturing and toolmaking.
The laser hardening is a process in which the energy input takes place by means of radiation directly to the component surface. The laser beam heats short term and localized the top portion of the workpiece up to the austenitizing temperature of the material used. This leads to a homogenization of the carbon distribution and thus to a spread of a front of austenitization in the material. Depending on the material used, the austenitizing temperature is about 900 ° C to 1400 ° C and time to temperature at about 3 s to 10 s. |
