Abstract

In the literature, there are experimental studies, confirming the significant effect of the degree of concentration of the active components of corrosive medium on the corrosion process. These results are presented in tables and graphs that describe the dependencies of the time before corrosion damage on the mechanical stress and the concentration of the diffusing substances. Functional dependencies, describing these data are of limited use. However, establishing a more general analytical dependency is necessary to study the corrosion process mechanism. As a result of the analysis of experimental data, a universal function-formula of corrosion strength of materials, which allows to forecast the "material - corrosive medium" system properties with regard to the action of mechanical stress and concentration of diffusing substances was proposed. A system of experiments, allowing to determine the universal constants, which are contained in the proposed function was formulated. The results of processing the experimental data on corrosion damage, borrowed from the literature were presented. The proposed formula can be used as a universal function-characteristic of the "material - corrosive medium" system. It can also be used in constructing phenomenological theories of corrosion damage of materials.
