INFLUENCE OF LASER BEAM HARDENING UPON ITROCARBURATE COATINGS
Keywords:
nitrocarburising, laser, beam, microsructures, microhardnessAbstract
The laser appliance used also for superficial hardening is made – in principle – of a reflecting
cavity calledresonator, with special mirrors and a reflecting capacity that is basically zero. These
are positioned face to face and filledwith a special active medium – in solid, liquid or gaseous
state – in which the phenomenon of electron population inversionmay take place.The paper
present the influence of laser beam hardening upon nitrocarburate structures. Research was
madeon two categories of carbon steel for buildings namely C 30 and C 45. After
nitrocarburising was made a laserhardening.
