Abstract
U ovo diplomskom radu obrađena je tema utjecaja alternativnih otapala na koroziju čelika u morskoj vodi. Korozija je nepoželjno trošenje konstrukcijskih materijala kemijskim djelovanjem okoline te predstavlja pretvaranjevelikog broja korisnih metala u nekorisne spojeve pa čak i štetne korozijske produkte. U teorijskom dijelu rada navedene su vrste nehrđajućih čelika za primjenu u morskoj vodi, opisana su njihova svojstva te primjena. Također su opisane vrste korozijskihoštećenja u morskom okolišu te su navedene legure koje imaju otpornost prema pojedinim vrstama korozije. Kako bi se osigurala dugotrajnost i korozijska otpornost površine metala, razvijene su različite metode zaštite koje su objašnjene u dijelu osnove zaštite metala.Na kraju teorijskog dijela govori se o eutektičkim otapalima, njihovom sastavu i svojstvima, teionskim kapljevinama. U eksperimentalnom dijelu rada ispitan je utjecaj prirodnih eutektičkih otapala na koroziju nehrđajućeg čelika X6CrNiTi18-10u 3% otopini NaCl. Za određivanje brzine korozije koristila se gravimetrijskametoda, dok se metodom elektrokemijske impedancijske spekrtroskopijeodredilo ponašanje čelika u 3% NaCl s dodatkom ispitivanih prirodnih eutektičkih otapala (NADES). Da bi se dokazalo djelovanje ispitivanih prirodnih eutektičkih otapala na koroziju čelika u 3% NaCl, površine uzoraka čelika snimljene su optičkim metalografskim mikroskopom.
Abstract (english)
The subject of this thesis is the effect of alternative solvents on the corrosion of steel in sea water. Corrosion is unwanted wearing of construction materials by chemical influence of its environment. It represents conversion of useful materials into unuseful compounds and even into harmful corrosion products. The types of noncorrosive steels that are used in sea waters, their features and application are described in theoretical part of thesis. The subjects of this part are also types of corrosion damages in sea environment and types of alloys that are resistant to various types of corrosion. In order to ensure the longevity and corrosion resistance of the metal surface, various protection methods have been developed and explained in the section on the basics of metal protection. In the end of this part it is written about eutectic solvents, their compound and features, and about ionic liquids. The gravimetric method was used to determine the corrosion rate, while the behavior of stainless steel in 3% NaCl was determined by the method of electrochemical impedance spectroscopy with the addition of tested natural eutectic solvents (NADES). To prove the effect of the tested natural eutectic solvents on the corrosion of steel in 3% NaCl, the surfaces of the steel samples were imaged with an optical metallographic microscope.
