Abstract
Ugljični čelik je materijal koji zbog svojih svojstava i cijene ima mnogo različitih namjena. Nedostatak ovog materijala je taj što nema otpornost prema koroziji. Vrlo često se zbog toga na ugljični čelik nanose različite prevlake. U ovom radu praćena je migracija iona kroma, nikla i bakra iz prevlaka na ugljičnom čeliku koji je korišten za izradu nakita. Nakit od čelika je stavljan u kontakt s modelnom otopinom znoja da bi se simulirali uvjeti koji nastaju prilikom nošenja nakita uslijed interakcije kože (znoja) i nakita. Dobiveni rezultati su pokazali da postoji značajna migracija navedenih iona u otopinu znoja. Koncentracija migriranih iona ovisi o vremenu kontakta nakita i otopine, ali i o debljini prevlake i eventualnim oštećenjima na nakitu. Za usporedbu rezultata provedena su identična istraživanja na nakitu koji je napravljen od nehrđajućeg čelika.
Abstract (english)
Carbon steel is a material that is widely used for various purposes due to its properties and price. However, it is not resistant to corrosion, which is one of the major drawbacks. Therefore, different coatings are often applied to carbon steel. In this graduate thesis, the migration of chromium, nickel and copper ions from coatings on carbon steel used for jewellery making was monitored. Steel jewellery was placed in contact with a model solution of sweat to simulate the conditions that occur during the interaction of jewellery and skin perspiration. The obtained results showed that there is a significant migration of these ions into the perspiration solution. The concentration of migrated ions depends on the contact time of the jewellery and the solution, but also on the thickness of the coating and possible damage on the jewellery. To compare the results, identical studies were performed on jewellery made of stainless steel.
