Abstract
Primjena inhibitora korozije vrlo je zastupljena i važna metoda zaštite metalnih konstrukcija od pojave korozije. Njihovoj primjeni prethode mnogobrojna testiranja u laboratorijskom ili realnom okruženju. Budući da broj kreiranih inhibitora raste iz dana u dan, razvoj metoda za ispitivanje njihova mehanizma djelovanja, ekološke prihvatljivosti, zadržavanja na metalnim površinama i same učinkovitosti predstavljaju veliki izazov. U ovom radu prikazan je razvoj metode za ispitivanje zadržavanja parnofaznog inhibitora korozije na aluminiju uz simuliranje kloridima izazvane korozije. Proveden je kontaktni test i nekontaktni testovi u tekućoj i plinovitoj fazi. Razvijana je metoda indikacije zadržavanja inhibitora otopinom bakrovih iona. Uzorci su podvrgnuti mikroskopskim analizama, određivanju gubitka mase aluminijevih pločica i količine otopljenog aluminija u otopinama, te elektrokemijskim mjerenjima potencijala otvorenog kruga i elektrokemijske impedancijske spektroskopije. Provedeni niz testova smatra se početkom razvoja nove metode za ispitivanje zadržavanja parnofaznog inhibitora korozije na metalnoj površini. Perspektiva simuliranja kloridima izazvane korozije u parnoj fazi je u načinu nanošenja klorida na pločice uranjanjem u otopinu natrijeva klorida čija se koncentracija može optimirati.
Abstract (english)
The application of corrosion inhibitors is an important method of protecting metallic structures from corrosion. Their application is preceded by numerous tests in a laboratory or real environment. Since the number of created inhibitors is growing daily, the development of methods for testing their mechanism of action, ecotoxicity, metal surface retention and efficiency is a great challenge. This paper presents the development of a method for testing the retention of the vapor phase corrosion inhibitor on aluminum by simulating chloride-induced corrosion. Contact test and non-contact tests in liquid and vapor phase were performed. The method of indicating the retention of the inhibitor by a solution of copper ions was developing. Samples were submitted to microscopic analysis, measurement of mass loss of aluminum plate and amount of dissolved aluminum in solutions and electrochemical measurements (open circuit potential, electrochemical impedance spectroscopy). The series of tests carried out is considered to be the beginning of the development of a new method for testing the retention of the metallic surface corrosion vapor phase inhibitor. The perspective of simulating chloride-induced corrosion in the vapor phase is in the method of depositing chloride on the metal plates immersion plates in a solution of sodium chloride whose concentration can be optimized.
