Sažetak
Otpornost prema koroziji aluminijumske legure serije 7000 ispitivana je primenom različitih elektrohemijskih metoda. Legura je bila podvrgnuta jednostepenom i novom dvostepenom termičkom taloženju. Polarizaciona merenja u 3,5 mas.% NaCl su pokazala da legura posle dvostepenog termičkog taloženja ima pozitivniju vrednost potencijala pitinga (Epit) i veću otpornost prema koroziji. Spektroskopija elektrohemijske impedancije (SEI) je takođe pokazala da legura posle dvostepenog termičkog taloženja ima bolju otpornost prema koroziji (veću vrednost polarizacione otpornosti, Rp i manju vrednost kapacitivnosti dvojnog sloja, Cdl) u poređenju sa legurom posle jednostepenog termičkog taloženja.
