Abstract

Przedmiotem zgłoszenia jest sposób formowania warstw tlenkowych gdzie element z aluminium lub jego stopu poddaje się polaryzacji anodowej w kąpieli krzemianowej, boranowej, heksametafosforanowej lub ich mieszaninie, korzystnie zawierającej krzemian sodu lub potasu o stężeniu od 1 do 120 g/dm3, tetraboran sodu lub potasu o stężeniu od 1 do 120 g/dm3 heksametafosforan sodu lub potasu o stężeniu od 1 do 240 g/dm3 wodorotlenek sodu lub potasu o stężeniu 0,3 do 30 g/dm3 prowadzonej w warunkach prądu stałego lub impulsowo przy zachowaniu gęstości prądu od 0,1 A/dm3 do 50 A/dm2, napięcia dodatniego od 250 do 800 V oraz napięcia ujemnego od 0 do —150 V, przez czas od 5 do 120 min, korzystnie płucze w wodzie destylowanej i suszy charakteryzuje się tym, że tak utleniony element zanurza się w ciekłym monomerze polimerowego inhibitora korozji aluminium, a po jej wyciągnięciu i wysuszeniu poddaje powtórnie procesowi polaryzacji anodowej, co skutkuje podniesieniem odporności korozyjnej podłoża metalowego.The subject of the application is a method of forming oxide layers where an element of aluminum or its alloy is subjected to anodic polarization in a silicate, borate, hexametaphosphate bath or their mixture, preferably containing sodium or potassium silicate with a concentration of 1 to 120 g / dm3, sodium or potassium tetraborate with concentration from 1 to 120 g / dm3 sodium or potassium hexametaphosphate with a concentration from 1 to 240 g / dm3 sodium or potassium hydroxide with a concentration of 0.3 to 30 g / dm3 conducted under constant current conditions or pulsed while maintaining current density from 0.1 A / dm3 to 50 A / dm2, positive voltage from 250 to 800 V and negative voltage from 0 to -150 V, for a period of 5 to 120 minutes, preferably rinsed in distilled water and dried, characterized by immersing the oxidized element is contained in the liquid monomer of the polymer corrosion inhibitor of aluminum, and after it has been pulled out and dried, it is subjected to the anodic polarization process again, which results in increasing the corrosion resistance of the metal substrate that.
