Corrosion – the main electrochemical process damaging metal materials. The combination of cyclic stresses and corrosive environment causes wear-fatigue damage called corrosion-mechanical fatigue. The paper studies the problem of forecasting this type of wear-fatigue damage, which occurs practically in all branches of engineering, especially in the chemical, oil, metallurgical industries, in transport. The work is done in 3 parts. In the first part, a technique for estimating the endurance limit in a given medium (direct effect) has been developed. In the second part, a technique for predicting corrosion-erosion damage is proposed depending on the magnitude of the operating stresses (back effect). The third part discusses mechanisms of corrosion-mechanical fatigue.
