Abstract
Ispitivanja su izvršena na aluminijskoj AlMg leguri (oznake AA 5754) koja se u prehrambenoj industriji koristi za izradu limenki za pakiranje piva i bezalkoholnih gaziranih pića. Korozijsko ponašanje legure ispitano je u nekoliko različitih vrsta piva, kao što su Karlovačko svijetlo pivo, Karlovačko tamno pivo i Pittinger svijetlo pivo. Obzirom na sastav, promatrana pića se mogu podijeliti na: piva ječmene baze (Karlovačko svijetlo i Karlovačko tamno pivo) te piva pšenične baze (Pittinger svijetlo pivo). Ispitivanja su provedena praćenjem vremenske promjene potencijala otvorenog strujnog kruga, primjenom linearne i potenciodinamičke polarizacijske metode, a oštećenja na površini metala nastala polarizacijom potvrđena su optičkim mikroskopom. U ispitivanim pivima korozijska otpornost AA 5754 legure raste redom: Karlovačko tamno pivo < Karlovačko svijetlo pivo < Pittinger svijetlo pivo. Naime, istim redom smanjuje se korozijska struja, a povećava polarizacijski otpor. U svim promatranim pivima brzina korozije AA 5754 legure može se smatrati zanemarivo malom (čak je za 2-3 reda veličine manja od vrijednosti dopuštene u praksi).
Abstract (english)
The tests in this paper were performed on aluminum AlMg alloy (marks AA 5754), which is used in the food industry for the production of cans for packaging beer and non-alcoholic carbonated drinks. Corrosion behavior of the alloy was tested in several different types of beer, such as Karlovačko light beer, Karlovačko dark beer and Pittinger light beer. Considering the composition, the observed drinks can be divided into: barley-based beers (Karlovačko light and Karlovačko dark beer) and wheat-based beers (Pittinger light beer). The tests were carried out by monitoring the time change of the open circuit potential, using the linear and potentiodynamic polarization methods, and the damage on the metal surface caused by polarization was confirmed by a light microscope. In the examined beers, the corrosion resistance of the AA 5754 alloy increases in the following order: Karlovačko dark beer < Karlovačko light beer < Pittinger light beer. Namely, the corrosion current decreases in same order, while the polarization resistance increase. In all observed beers, the corrosion rate of the AA 5754 alloy can be considered negligibly small (it is even 2-3 orders of magnitude lower than the value allowed in practice).
