Abstract

Department of Chemistry and Labor Protection, Volodymyr Dahl East Ukrainian National University, 59-a, pr. Central.,93400, Severodonetsk Department  of Theoretical  Engineering  and Industrial  Enterprises, Volodymyr  Dahl East  Ukrainian  National  University,  59-a, pr. Central, 93400, Severodonetsk Electrochemical defense by cathode polarization together with isolating coverage −for today is most effective from all methods  of  fight  against  corrosion.  Essence  of  electrochemical  defense  consists  in  deceleration  of  corrosive  processes,  mainly electrochemical. Cathode defense −conducted by means of direct-current from outsourcing at that object that is subject todefense joins negative to the pole of the station of cathode defense (in quality to the cathode), and the sacrificial anode of grounding joins in with a positive pole. Setting of cathode defense is building which is used for cathode polarization of pipeline by an external current. By settings of cathode defense (UKZ) which polarizes a pipeline, corrosive processes are taken to the minimum value or quite halted. A surface of pipeline is in defense and does not collapse in an aggressive environment during great while or destructive processes are  taken  to  the  minimum  values. The  structural  changes  of  metal  and  changes  of  mechanical  descriptions  of  the  steel  anodic grounding conditioned to these, stations of cathode defense, made from material of Stal'20 Du159, were investigated in our work.
