Abstract

Reflection IR spectroscopy, atomic force microscopy (AGM), and electrophysical measurements were used to investigate the formation of surface oxide nanostructures during the radiation oxidation of metallic aluminum in contact with water. It is revealed that the radiation modification of the surface relief is accompanied by the formation of oxide nanolayers, the defectiveness of which is determined by the irradiation time. It is shown that the formation of oxide nanolayers in the region of absorbed dose (0.5-120 kGy) occurs in three stages, which is accompanied by a decrease in electrical conductivity by 5 orders and an increase in the thickness of the oxide layer by an order of magnitude. The role of surface intermediate-active particles in the formation of oxide nanostructures is considered.
