Resumo

The results of experimental studies of the effect of residual magnetization on the corrosion of steel samples in an aqueous medium are presented. Algorithms of research and processing of results are described. Three cases of initial magnetization of samples are considered. It is established that before the critical magnetization of steel samples, the corrosion wear in the aqueous medium decreases, and then begins to grow. The discovered effect is of great theoretical importance in studying the phenomenon of corrosion, taking into account the initial residual magnetization, as well as of great practical importance, in particular, in the design and operation of various structures and structures made of steel to protect them from corrosion destruction.
