First sentence: electric are atmosphere, through intermediate layers of carbides and oxycarbides. The latter phenomenon explains a strong adhesion, without any separation, of the oxide films to the cathode and a good electrical contact between the graphite holder and the emissive film which is an alloy of de-stoichiometric oxides with an oxygen defect.
