Abstract

Korozija ili oksidacija je nezaustavljiv, spontan proces razgradnje materijala koja uzrokuje
velike materijalne i financijske posljedice. U cilju spriječavanja razvoja korozije i šteta koje
prouzročuje, velika se količina materijalnih sredstava i znanja ulaže u proučavanje nastanka i
sprečavanja iste. Ovisno o mjestu i uvjetima eksploatacije razvile su se razne metode zaštite od
korozije koje zahtjevaju različite načine nanošenja kao i metode pripreme pred nanošenje. U
eksperimentalnom dijelu završnog rada izrađeni su uzorci od aluminijske legure tipa 5086, te
su pripremljeni s pet različitih metoda pripreme prije nanošenja antikorozijske prevlake
metodom elektrostatskog naprašivanja. U svrhu ispitivanja kvalitete i svojstava prevlake, uzorci
su bili podvrgnuti ubrzanim korozijskim ispitivanjima u slanoj i vlažnoj komori koje
reprezentiraju višestruko duža vremena eksploatacije no što je vrijeme ispitivanja u komorama.
Prije ispitivanja u komorama kao i poslije, ispitana je prionljivost prevlake te otpornost iste na
udarna opterećenja. Rezultati ispitivanja su analizirani te su izvedeni zaključci.

Abstract (english)

Corrosion or oxidation is an unstoppable, spontaneous process of material decomposition which
causes major material and financial consequences. In order to prevent the development of
corrosion, and the damage it causes, a large amount of material resources and knowledge is
invested in the study of its origin and prevention. Depending on the place and conditions of
exploitation, various methods of corrosion protection, which require different methods of
application as well as methods of preparation before application, have been developed. In
research that was conducted, samples were made of aluminum alloy type 5086, and prepared
with five different methods of preparation before applying the anti-corrosion coating by the
method of electrostatic spraying. In order to test the quality and properties of the applied
coatings, the samples were exposed to accelerated corrosion tests in salt and wet chambers,
which represent many times longer service life than time exposed in the chambers. Before and
after testing in the chambers, adhesion of the coating and the resistance of the coating to impact
loads was tested.
