METHOD AND DEVICE FOR DETECTING ELECTROCHEMICAL DEPOSITION Russian patent published in 2021 - IPC G01N27/60 G01N17/02 

FIELD: anti-corrosion measures.

SUBSTANCE: invention relates to the field of electrochemical protection of underground structures against corrosion and is intended to work as part of a cathodic protection system to detect the fact of metal corrosion, for example, pipelines. The method for detecting electrochemical copper deposition includes periodic measurement of the natural potential between the remote electrode and the copper sulfate reference electrode ΔU_1i, while additionally, with the same measurement period of the natural potential between the external electrode and the copper sulfate reference electrode ΔU_1i, the natural potential between the copper electrode and the copper sulfate reference electrode ΔU_2i is measured, the difference calculated between the obtained values ​​ΔU_1i and ΔU_2i, the obtained difference is compared with the difference of the previous calculations ΔU_1i-1 and ΔU_2i-2 and when ΔU_1i - ΔU_2i → 0, the beginning of electrochemical copper deposition on the external electrode is announced.

EFFECT: possibility of operational control of electrochemical deposition of copper on remote electrodes in cathodic protection systems for metal structures.
