摘要：
FIELD: physics.SUBSTANCE: invention relates to control over corrosion processes and can be used for continuous control of pitting corrosion and its penetration into inner walls of metal structures (evaporators, reactors, heat exchangers, tanks, pipelines, and so forth) in contact with electroconductive corrosive media under conditions when it is impossible to avoid development of pitting corrosion. Method of continuous control of pitting corrosion of inner walls of metal structures in corrosive medium includes placement in it of an indicator electrode made of material of internal wall of equipment, which is additionally introduced into corrosive medium of auxiliary electrode is anodically polarized in galvanostatic mode until formation of stable pitting on surface of electrode, thereafter, the indicator electrode is synchronously disconnected from the direct-current source and connected through a current-measuring device to the wall, wherein continuous control of pitting corrosion is performed based on the cu
