Тhe transformation of the oxide coatings of aluminum by imitation factors of nuclear power plants

Abstract

The authors present the results of a study on kinetics of hydrogen generation by heterogeneous compositions with aluminum exposed to γ-irradiation in air, in different aqueous solutions at room temperature and high temperature annealing. It has been found that hydrogen generation kinetics depends on the γ-irradiation dose, temperature and aqueous medium chemistry. Changes in hydrogen generation kinetics are due to transformations of aluminum oxide coatings influenced by factors simulating the NPP conditions. The effect of metal oxide coating transformations should be considered in predicting the corrosion resistance of NPP structural materials.
