Fracture resistance of structural steels after laser alloying and nitriding

  • S. A. Kunavin
  • O. V. Chudina


The resistance of low-carbon steel to static and fatigue fracture after a combined process of surface hardening including laser alloying followed by nitriding is analyzed on the basis of concepts of a structural theory of strength and by methods of fracture mechanics. The efficiency of the process is proved from the standpoint of an optimum combination of characteristics determining the structural strength of the steel.
