Acceleration of Solid-Phase Chromizing of Steel by Intrinsic Thermionic Field

Metal Science and Heat Treatment Aims and scope

The possibility of acceleration of processes of thermal diffusion chromizing of steels by introducing additions (electron and oxygen anion emitters) into the saturating mixture is considered. A microscopic x-ray spectrum analysis of specimens chromized in powder mixtures with and without emitters is performed. The composition and the thickness of the diffusion layer are determined. It is shown experimentally that electric current emerges in the filler at the saturation temperature. The influence of the intrinsic thermionic field on the diffusion processes is explained.
