Способ относится к диагностике коррозионной устойчивости алюминиевых сплавов. Изобретение заключается в следующем. Впервые с помощью рентгеновской электронной спектроскопии выявлен сегрегационный эффект элементов на поверхности алюминиевых сплавов при воздействии циклической деформации, используемый для диагностики коррозионных отказов алюминиевых сплавов для повышения его экспрессности. На выборке образцов с известной величиной циклической деформации определяют содержание элементов на поверхности методом рентгеновской электронной спектроскопии. Для исследуемых образцов партии определяют содержание на поверхности легирующих элементов. Устойчивость сплава к расслаивающей коррозии определяют по градуировочной зависимости склонности к расслаивающей коррозии, выраженной в баллах по десятибальной шкале, от содержания легирующих элементов и кислорода на поверхности сплава.The method relates to the diagnosis of corrosion resistance of aluminum alloys. The invention consists in the following. For the first time, X-ray electron spectroscopy revealed the segregation effect of elements on the surface of aluminum alloys under the influence of cyclic deformation, which is used to diagnose the corrosion failures of aluminum alloys to increase its expressivity. On a sample of samples with a known cyclic strain value, the content of elements on the surface is determined by X-ray electron spectroscopy. For the studied samples of the party determine the content on the surface of the alloying elements. The resistance of the alloy to exfoliating corrosion is determined by the calibration dependence of the tendency to exfoliating corrosion, expressed in points on a ten-point scale, on the content of alloying elements and oxygen on the surface of the alloy.
