Аннотация:Surface layers formed at a contact of chromium with sulfuric acid solutions containing some organic substances (sodium oxalate, dimethylformamide, methanol) are analyzed by the X-ray photoelectron spectroscopy method. The layers are shown to contain products of deep destruction of organic molecules, i.e. carbon species and those containing functional groups. The data obtained point to the electrocatalytic activity of chromium in cathodic processes. The results of this study may provide a deeper insight into the mechanism of carbon incorporation (in the form of carbide compounds as well) into amorphous chromium deposits formed in sulfuric acid baths containing some organic substances.
