Abstract

At present, the issue of developing methods for predicting the change in the strength properties of structural aluminum alloys used in the composition of structural elements in conditions of environmental factors for long periods of operation is topical. In this case, the key is to search for the principal approaches to predicting the corrosive behavior of aluminum alloys as materials for which uneven corrosion damage is characteristic, and assessing the complex effect of the most dangerous types of local corrosion on the change in the mechanical properties of aluminum alloys. The calculation of the integral coefficient of corrosion failure based on the predicted values of the main corrosion characteristics of aluminum alloys-loss of weight, depth of pitting and intercrystalline corrosion, as well as the tendency to delaminating corrosion, has been performed. It is shown that the application of the method of calculating the integral corrosion coefficient can be used to obtain the pred
