20.500.12556/DiRROS-28581 Review of coatings used for corrosion protection of aluminium alloys Aluminium and aluminium alloys are major technological metals, offering desirable mechanical properties, low density, thermal and electrical conductivity. Importantly, they exhibit high recyclability. While these materials are relatively stable and corrosion-resistant in most environments, they are often subjected to corrosion and wear in harsh environments. Coatings are the most common method of corrosion protection of aluminium and its alloys. Coatings can improve not only corrosion resistance but also wear resistance, and can add functional properties to the surface. In the present review, the coatings are summarised in five groups: (1) barrier aluminium oxide coatings, including anodised coatings, plasma electrolytic oxidised coatings, coatings deposited by atomic layer deposition, and by hydrothermal treatment, (2) conversion coatings including zirconium, chromate, titanium, trivalent chromium, and phosphate (3) metallic coatings comprising clad and electroplated metal coatings, (4) organic coatings comprising powder and liquids organic coatings, and sol–gel coatings, and (5) inhibition and wettability control coatings, comprising coatings incorporating inhibitors or nanoparticles and superhydrophobic coatings. The review focuses on production methodologies and the physical-chem-ical characteristics of coatings. Advantages and potential shortcomings of individual coatings are discussed in terms of their use and corrosion protection. Aluminij in aluminijeve zlitine so pomembne tehnološke kovine, ki ponujajo zaželene mehanske lastnosti, nizko gostoto, toplotno in električno prevodnost ter izkazujejo visoko stopnjo recikliranja. Čeprav so ti materiali večinoma relativno stabilni, so v zahtevnih okoljih izpostavljeni koroziji in obrabi. Prevleke so najpogostejša metoda zaščite aluminijevih zlitin pred korozijo. Prevleke lahko izboljšajo tudi odpornost proti obrabi in površini dodajo funkcionalne lastnosti. V tem preglednem članku so prevleke za aluminijeve zlitine povzete v pet skupin: (1) barierne prevleke iz aluminijevega oksida, pripravljene z anodno oksidacijo, plazemsko-elektrolitsko oksidacijo, nanašanjem atomskih plasti in s hidroter-malno obdelavo, (2) konverzijske prevleke na preveleke na osnovi kromata, cirkonija, titana, trivalentnega kroma ali fosfata, (3) kovinske prevleke, (4) organske in hibridne sol-gel prevleke, in (5) prevleke, ki vsebujejo dodatke, ki zavirajo korozijo ali povečujejo omočljivost površine. Pregled se osredotoča na proizvodne metodologije in fizikalno-kemijske lastnosti prevlek. Obravnavane so prednosti in morebitne pomanjkljivosti posameznih prevlek z vidika njihove uporabe in zaščite pred korozijo. true false true Slovensko kemijsko društvo Slovenija Angleški jezik Slovenski jezik Copyright (c) 2026 Ingrid Milošev, Ana Koblar Neznano 2026-03-24 13:42:05 2026-03-24 13:42:05 2026-03-27 03:47:32 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Opis vira z dne 23. 3. 2026; str. 11-30 no. 1 Vol. 73 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-12-20 0000-00-00 2026-02-23 620.1/.2 1580-3155 10.17344/acsi.2025.9686 272799235 https://acsi-journal.eu/index.php/ACSi/article/view/9686 1 deef1f28-277e-11f1-aa40-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42431 RAZ_Milosev_Ingrid_2026.pdf RAZ_Milosev_Ingrid_2026.pdf 1 5A97D16AD8F5E3914AD2B1392F283A86 39ba89b0e9625fb03252d1e460a5f9c96a9108ef8ed74cdd153b3200fea24a21 2b0dc94b-277f-11f1-aa40-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42432 Institut Jožef Stefan 0 0 0
