Abstract
AbstractFor the description of reactions between solids and gases it is important to investigate the compositional changes in the surface of the solid as a function of temperature and reaction time. Conventional methods of surface analysis cannot be applied in such investigations under atmospheric pressure. We have used the techniques of thermal analysis by emission spectrography (TESG) and of X‐ray photoelectron spectroscopy (ESCA). Work with aggressive gases under atmospheric pressure was done in a special reactor, connected by a vacuum‐lock directly to the ESCA spectrometer. Thus we have been able to establish characteristic reaction temperatures in the BCl3/H2/steel system and to assign them to certain surface changes. From that a model for the initial phase of the formation of the boride layer on a plain carbon steel has been derived.
