Information system support for vacuum furnaces and technology

The original idea of the grain coarsening inhibition by preliminary nitriding preceding the vacuum carburizing process is a useful option of FINECARB technology. The steel vacuum carbinitriding method based on the alternative dosing of the carbon carriers and nitrogen, and on the computer simulation of the layer growth under the conditions of unsteady concurrent diffusion of the nitrogen and carbon is presented in this paper. The application examples are also described.
