The coatings are used for corrosion protection in a variety of industrial applications. In this study, the accelerated corrosion behavior of Zn, Al and Zn/15Al coatings on a steel surface during the salt-spray testing period was investigated. The surfaces ofsteel coupons were coated with Zn, Al and Zn/15Al using the TWEA spray-deposition system. The corrosion test was performed in a chloride atmosphere in a salt-spray test for over 2000 h. The corrosion of samples is assessed as the ratio of the corroded area of the specimens. The salt-spray test results showed that Al and Zn/15Al coatings have a better corrosion resistance than Zn coatingsZn, Al in Zn/15Al prekritja lahko pripravimo v optimalnih pogojih s tehniko dvožičnega ločnega brizganja (RWEA). Prekritja se uporablja za zaščito proti koroziji pri različnih industrijskih uporabah. V tem delu smo raziskali pospešeno korozijsko obnašanje Zn, Al in Z/Al prekritij na površini jekla z metodo slanega naprševvanje. Površina vzorcev jekla je bila prekrita z Zn, Al ali Zn/Al prekritjem s TWEA sistemom depozicije. Preizkus v kloridni atmosferi in naprševanjem je trajal 2000 ur. Korozija je bila ocenjena kot delež korodirane površine vzorcev. Preizkusi so pokazali da imata večjo korozijsko obstojnost pri slanem naprševanju prekritji A in Zn/15Al kot prekritje ZnTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
