NOMOGRAPHS OF THE NONLINEAR PROCESS OF NITRIDING

The article presents nomographs for the nitriding of carbon steels obt ained by calculation of a nonlinear model of diffusion with a view to the dependence of the diffusion coefficients of carbon and nitrogen on the concentration of these elements in the steel. The nomographs prov ide more complete information on the conditions and results of nitridi ng. The suggested method of calculation of the nonlinear model of nitr iding can also be used (upon change of the corresponding initial data) for constructing nomographs for the most variegated processes of ther mochemical treatment involving saturation from the gaseous phase.
