Description

Influence of chemical elements as impurities in steels on erosion-corrosion wear (ECW) of NPP equipment and piping is considered. Calculated dependences and tables provided permit ascertaining the influence of impurities (chromium and copper) and their content on ECW for considered range of their content in steels. Impurity elements, chromium in particular, in steels increase service life characteristics of elements of NPP equipment and piping during ECW

Abstract (Russian)

Рассмотрено влияние химических элементов, являющихся примесями в сталях, на эрозионно-коррозионный износ (ЭКИ) оборудования и трубопроводов АЭС. Приведенные расчетные зависимости и таблицы позволяют определить влияние содержания примесных элементов (хрома и меди) на скорость ЭКИ в рассмотренном диапазоне их содержания в сталях. Наличие примесных элементов, особенно хрома в стали, повышает ресурсные характеристики элементов оборудования и трубопроводов АЭС при ЭКИ
