| Résumé : | Treatment of solid cadmium at temperatures near its melting point in a low partial pressure of oxygen strongly modifies the behavior of the metal during subsequent oxidation in the domain within which nucléation of cadmium oxide takes place. The observed facts-multiplication of the number of oxide nucléation sites, disappearance of the incubation period and a displacement of the nucléation domain towards low partial oxygen pressures-are attributed to a dissolution of oxygen in the cadmium. These results confirm the mechanism proposed by Bérnard and his collaborators which state that the formation of oxide nuclei is attributed to a supersaturation of oxygen in the surface layer of the metal. © 1963. |
