3. Superficial treatments using high-energy-density beams

3.1 Possibilities offered by high energy density beams

New high-energy density sources such as lasers or electron beams [M 1 240] are of growing interest in the field of surface treatment of tool steels, as they enable extremely localized reinforcement, thus reducing the dimensional variations caused by conventional thermal or thermochemical treatments, and saving the input of costly alloying elements.

Lasers and electron beams are practically...
