Sažetak
U ovom radu je izvršeno ispitivanje ponašanja Al-Yn legura u rastvorima hlorida različitih koncentracija, uz dodatak legirajućih mikro elemenata indijuma, galijuma i bizmuta. Pored ovih elemenata vršilo se legiranje i sa kalajem. Tako dobijene legure aluminijuma su ispitivane na dodatne korozione i elektrohemijske testove kako bi se videla mogućnost proizvodnje žrtvenih elektroda. U pripremi postupka na kome bi se baziralo ovo, polazi se od činjenice da postoji veliki broj uticajnih faktora, počev od hemijskog sastava, postupka topljenja, legurajuće i livene metode, koje bi omogućile dobijanje visoko kvalitetnih legura koje mogu da se efikasno koriste kao protektori.
Abstract
This work was carried out of behavior of Al-Zn alloy systems in chloride solutions of different concentrations, with additional alloying indium, gallium and bismuth as micro alloying elements. In addition to these elements is done by the alloying with tin. Thus obtained aluminum alloy with additional corrosion and electrochemical tests give a chance to produce their own sacrificial electrodes. In preparing the concept on which this paper is based, started from the fact that there are a number of influential factors, starting from the chemical composition, methods of melting, alloying and casting methods that would allow obtaining high-quality alloy that can be effectively used as a protector.
