Abstract
Examination of lead–indium and lead–tin alloys by X-ray photo-electron spectroscopy has provided an insight into the way in which these materials resist corrosion. The tin and indium are found to be markedly segregated at the surfaces, in oxidized form. The alloying elements additionally promote the formation of a form.of lead (thought to be PbO2) more highly oxidized than that obtained on the surfaces of pure lead under the same conditions.
