1 March 1995 Laser treatment of 38HMJ steel surfaces in an Ar:N2 plasma environment
Author Affiliations +
Samples of 38HMJ steel predestined for nitriding under an eutectoid point have been laser- processed in a flow of Ar:N2 mixture with and without the continuous optical discharge sustained over the sample surface. The resulting increase of microhardness is smaller than that observed for carbon steel samples under similar conditions. A model of the plasma in the vicinity of metal surface and results of temperature field calculations are also presented.
