Abstract

The corrosion of aluminium has been studied employing the irradiation in situ by neutrons from252Cf and gamma radiations from60Co. The effects of irradiation indicated the absence of pitting, suppression of the corrosion rate, i. e., quantitative reduction in corrosion when measured as weight loss as compared with unirradiated specimens. A protective grayish layer had emerged on the specimen surface which was akin to that formed in simulated experimental conditions carried out in presence of hydrogen peroxide. The possible mechanisms of the elimination of pitting and formation of grayish layer on the surface are discussed.
