Nitrogen and Carbon Saturation Kinetics of Powdered Materials Obtained by Hot Stamping in the Production of Complex Form Parts

Abstract

The processes occurring at saturation of the surface with various elannotation The paper deals with issues related to the kinetics of saturation of high-density powder materials obtained by hot stamping (GS). The effect of surface treatment, temperature and time of saturation of the surface of highdensity powder materials with nitrogen and carbon is investigated. The graphs of the influence of these factors are given. The structures of the diffusion layer and the effect of the surface features of high-density powder materials on saturation with nitrogen and carbon are described. Comparative studies on the saturation of the surface layer at the SC of high-density powder materials and rolled steels have been carried out. It is established that the thickness of the diffusion layer on the iron powder is greater than that on low-carbon electrical steel and the magnitude of the difference slightly decreases with increasing temperature.
