Effect of high-power ion beam irradiation modes of magnesium on the chemical composition of the surface layers at long-term storage in a surrounding atmosphere
Abstract:
The composition of the surface layers of magnesium irradiated (2015) by a high power ion beam of nanosecond duration under various conditions and after long-term storage in the surrounding atmosphere (2023) was studied. It was found that multiple irradiation of magnesium, leading to an increase in the surface relief, does not lead to a noticeable increase in the concentration of oxygen and atmospheric corrosion products in the surface layer compared to a single-irradiated sample. Using X-ray photoelectron spectroscopy, an increased carbon content in the surface layer of magnesium after irradiation, as well as the formation of the Mg–O–C bond, was established. Possible mechanisms of the influence of the composition of the irradiated surface layer of magnesium on the slowing down of its atmospheric corrosion are considered.
Keywords:high power ion beam, magnesium, atmospheric corrosion.
