Abstract

Ovaj diplomski rad sastoji se od dva dijela, teorijskog i eksperimentalnog.

U prvom dijelu teorijskog rada proučavaju se proces i sustav katodatne zaštite kao i mehanizam djelovanja u svrhu reduciranja i sprječavanja štetnih korozijskih procesa elektrokemijske naravi za konstrukcije od nelegiranog čelika. Objašnjen je proračun katodne zaštite te primjer katodne zaštite iz prakse.

U eksperimentalnom dijelu prikazani su simulirani uvjeti katodne zaštite u laboratoriju nu sustavu medija vodovodne i morske vode (3,5% otopina NaCl) te je, pomoću izvedenih mjerenja, donesena analize i zaključci koji se uspoređuju s podatcima prikazanima i naučenima iz literature. Ključne riječi: katodna zaštita, elektrokemijska zaštita, nelegirani čelik, morska voda, potencijal, anoda, redukcija

Abstract (english)

This thesis consists of two parts, theoretical and experimental.

In the first part of the theoretical work, the processes, systems of cathodic protection, and the mechanisms of action are studied to reduce and isolate harmful corrosion processes of an electrochemical nature for structures made of unalloyed steel. The calculation of cathodic protection and the preparation of cathodic defense is explained using an example from practice.

In the experimental part, the simulated conditions of cathodic protection in the laboratory in the medium system of tap and seawater (3.5% NaCl in water) are presented. With the help of the performed measurements, analyses and conclusions are drawn which are compared with the data shown and by scientists from the literature.
