Occurrence of Electric Field in Process of Solid-Phase Thermochemical Treatment of Products Made of Iron-Based Alloys

Abstract—The emergence of a thermionic field in a process mixture under thermal diffusion chromium plating has been established. It has been shown that some oxide compounds contained in a process mixture participate actively in the emission process. A cell for measuring emission currents and the temperature of their occurrence upon heating has been designed. The contribution of the electric emission field upon saturation of parts during thermochemical treatment has been determined in comparison with the contribution of the concentration field.
