    • Laser-beam carburizing of low-alloy steels 

      Katsamas, A. I.; Haidemenopoulos, G. N. (2001)
      The present study investigated the use of a laser-beam, in order to carburize the surface of DIN 15CrNi6 low-alloy, case-hardening steel. The surface of the material was coated with graphite prior to laser irradiation. Two ...

    • Surface hardening of low-alloy 15CrNi6 steel by CO2 laser beam 

      Katsamas, A. I.; Haidemenopoulos, G. N. (1999)
      The study investigates laser transformation hardening in the low-alloy 15CrNi6 case-hardening steel. The effect of process parameters such as beam power, beam diameter and travel speed on microstructure, case depth and ...
