The paper is concerned with the physicochemical processes of ion-electron interactions at the metal-oxide melt boundary during enamel coating formation. During the burning process on some spots on the surface of steel samples coated with enamel melt, there appear areas of intense metal oxidation with pronounced dark coloration in air atmosphere. It has been established that if in that place the melt is enriched with variable valence oxides to the extent that it becomes an electric conductor, the oxidation process is distributed in enamel melt at a constant rate over the entire metal surface. The speed at which the oxidation process spreads is determined by viscosity and composition of the melt. The paper presents the results of a study on the layer of metal-oxide melt adhesion using SEM.
