| 摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to field of cathode protection of metal objects against corrosion and can be applied for objects, which are in contact with electricity-conducting liquid. Device contains antenna electrode for supply of electrical load current into electricity-conducting liquid, protective electrode, source of protective current, electrically connected with conducting part of surface and protective electrode, with source of protective current being made with possibility of changing protective current in response to change in load current. Method includes supply of load current into electricity-conducting liquid, change of protective current in response to change in load current, with protective current flowing between electricity-conducting part of surface and protective electrode. Processor device contains computer programme for realisation of control of cathode protection of object by said method.EFFECT: invention makes it possible to increase efficiency of corrosion protection.11 cl, 2 dwg |
