Abstract
U ovom radu opisuju se postupci pasivacije aluminija, titanija i njihovih legura te nehrđajućeg čelika. Pasivacijom površine stvara se oksidni film koji štiti metale od agresivne okoline. Pregledom literature prikazani su različiti načini postizanja pasivacije metala. Spontanom pasivacijom aluminija nastaje oksidni film koji pruža dobru zaštitu u atmosferskim uvjetima dok anodnom oksidacijom nastaje deblji oksidni film otporan u agresivnim sredinama. Na površini titanija i njegovih legura oksidni fim dobrih svojstava nastaje anodnom oksidacijom ili eloksiranjem. Postupak pasivacije nehrđajućih čelika opisan je prema normama ASTM A380 i ASTM A967. Pasivnost nehrđajućeg čelika povećava se prisutnošću kroma kao i nikla, molibdena, titanija ili niobija. Također, naznačena je važnost primjene pasivacije jer povećava zaštitu materijala od korozije, produljuje vijek trajanja proizvoda, uklanja nečistoće s površine metala te smanjuje potrebu za održavanjem.
Abstract (english)
This paper describes the passivation processes for aluminum, titanium and its alloys, and stainless steel. Surface passivation involves the creation of an oxide film that protects the metals from an aggressive environment. A review of the literature shows that there are various ways of passivating metals. Spontaneous passivation of aluminum creates an oxide film that provides good protection under atmospheric conditions, while anodic oxidation creates a thicker oxide film that is resistant to aggressive environments. An oxide layer with good properties is produced on the surface of titanium and its alloys by anodic oxidation or anodization. The process of passivation of stainless steels is described in ASTM A380 and ASTM A967 standards. The passivity of stainless steel is increased by the presence of chromium as well as nickel, molybdenum, titanium or niobium. It also shows the importance of passivation, as it increases the corrosion protection of the materials, extends the life of the product, removes impurities from the metal surface and reduces the need for maintenance.
