Abstract

The surface of a workpiece is provided with a surface layer. Initially, the workpiece is inductively heated by a HF/MF generator to a first temperature and subsequently heated further by a laser beam with coating material being applied to the region of the laser beam in an amount sufficient to form a surface layer on the workpiece. The generator and the laser source are able to operate simultaneously to effect a high quality surface layer of relatively thin thickness.
