Round bar specimens of the CSN 12050 carbon steel,
which is equivalent to the German Ck 45 steel (DIN
17200/42; 1652), were normalized, or heat treated and
then surface processed without melting by a 2,5 kW,
COa laser to study the effects of laser beam
hardening on fatigue properties.
of ring laser beam traces were made: one and three
The fact, that laser beam hardening
under given conditions either reduces or does not
influence the fatigue life, which depends on the
surface finishing after the laser processing, is the
most important result of alternating bend fatigue
In recent years, several technologies of the laser
treatment of metal lie material...
