Abstract
Korozija predstavlja značajan problem za očuvanje kulturne baštine, a izloženost korozivnom okolišu može uzrokovati ozbiljno oštećenje ovih objekata. Korištenje premaza jedna je od brojnih metoda koje se danas provode kako bi se metalne konstrukcije zaštitile od korozije. Iako mnogi premazi osiguravaju dobru zaštitu, njihovo korištenje može doprinjeti onečišćenju okoliša zbog emisije hlapivih organskih tvari. S ciljem korištenja ekološki prihvatljivijeg rješenja za zaštitu metalnih materijala, u ovom radu ispitivana su svojstva vodorazrjedivog akrilatnog premaza na brončanoj površini u tri korozivna okoliša. Ispitivanja su provedena na uzorcima koji su bili kontinuirano ili ciklički izlagani simuliranoj kiseloj kiši, kao i vlažnoj komori u vremenskom periodu od 22 dana. Uzorci su periodički karakterizirani elektrokemijskim tehnikama - metodama linearne polarizacije i elektrokemijske impedancijske spektroskopije. Iz dobivenih rezultata je zaključeno da kod kontinuiranog izlaganja dolazi do pada zaštite u vremenu dok kod cikličko izlaganja dolazi do porasta korozijske zaštite.
Abstract (english)
Corrosion represents a significant problem for the preservation of cultural heritage and exposure to a corrosive environment can cause the serious damage to these objects. The application of coatings is one of the many methods used today to protect metal structures from corrosion. Although many coatings provide good protection, their widespread use can contribute to environment pollution due to the emission of volatile organic compounds. With the aim of using a more environmentally friendly solution for protection of metallic materials, in this work, the properties of acrylic waterborne coating on a bronze surface were examined in three corrosive environments. Measurements were conducted on samples that were either continuously or periodicaly immersed in simulated acid rain or exposed in condensation chamber over a period of 22 days. Samples were periodically characterized by electrochemical techniques –linear polarization method and electrochemical impedance spectroscopy. The obtained results showed that continuous exposure results in decrease of corrosion protection in time while cyclic exposure resulted in increase of corrosion protection.
