Abstract
U ovom radu ispitivana je raspodjela potencijala u ovisnosti o specifičnom otporu elektrolita za sustav katodne zaštite bazena izrađenog od niskougljičnog čelika pomoću titanske anode prevučene slojem miješanih oksida plemenitih metala kružnog presijeka. Za potrebe ispitivanja potencijala pomoću referentne Cu/CuSO4 elektrode izrađena je Lugginova kapilara koja se pokazala vrlo učinkovitom. Usporedbom raspodjele potencijala za konstantnu struju od 0,7A u tri različite koncentracije elektrolita: 0% NaCl, 0,5% NaCl i 1% NaCl vidljivo je da se s povećanjem koncentracije raspodjela širi po bazenu budući da se smanjuje specifični otpor elektrolita. Dobro raspoređene katodne zaštite pri najnižoj koncentraciji elektrolita skoro da i nema, vrijednosti zaštitnog potencijala vrlo malo prelaze granicu od -850mV, dok je za preostale dvije koncentracije cijela površina bazena pod katodnom zaštitom.
Abstract (english)
In this work was examined the distribution of potential as a funtion of electrolyte resistivity for a system of cathodic protection in a low carbon steel pool with a disk anode made of titanium and coated with a layer of noble metal oxides. For this purpose, a Luggin capillary with Cu/CuSO4 reference electrode was made and it proved to be efficient. By comparing the distribution of potential for the constant current of 0,7A in three different electrolyte concentrations of artificial sea water: 0% NaCl, 0,5% NaCl and 1% NaCl it is observed that by increasing concentration of electrolyte the distribution is spreading through the tank as the electrolyte resistivity is decreasing. Cathodic protection at the lowest electrolyte concentration is very poor because the values of protection potential are below -850mV. On the other hand, for the other two electrolyte concentrations the whole surface is under cathodic protection.
