Characteristics of new Oxide Films in Pure Aluminum

New Oxide Film formation in Aluminum alloys, have been studied by many researchers, because of their important role in defect formation in castings. But in the case of pure Aluminum, there are few published articles, In this research, characteristics (morphology and thickness) of new oxide films in pure aluminum have been studied using scanning electron microscopy (SEM) and samples have been made by O-M-O Sandwich technique. Results show that the oxide layer has folded surface morphology and the thickness of oxide film estimated as 100-150 nanometers.
