dc.description.abstract | The influence of the deposition parameters on the porosity of thin alumina films electrophoretically deposited on steel from aqueous suspensions was investigated. The effects of the applied voltage, deposition time, suspension temperature and the solid content of the aqueous suspension on the porosity of the obtained alumina films have been determined using optical microscopy coupled with image analysis. It was shown that the lowest film porosity was obtained from a suspension containing 20 wt.% alumina powder at the lowest applied voltage (30 V), for a longer deposition time (10 min) using a suspension temperature of 30 ºC. This behavior can be explained by the smaller amount of hydrogen evolved on the cathode during the electrophoretic deposition process. | en |
dc.description.abstract | Ispitivan je uticaj parametara taloženja, i to napona taloženja, vremena talo ženja, temperature suspenzije i koncentracije čvrste faze u suspenziji, na poroznost kataforetski taloženih tankih filmova iz vodene suspenzije praha aluminijum-oksida na čeliku.Poroznost dobijenih filmova određivana je primenom metode optičke mikroskopije uz analizu slike. Na osnovu dobijenih rezultata pokazano je da je najmanja poroznost prevlake aluminijum-oksida na čeliku dobijena pri taloženju iz vodene suspenzije koncentracije 20 mas%, pri naponu taloženja 30 V, za vreme taloženja 10 minuta i pri temperaturi suspenzije 30 °C.Ovakvo ponašanje moguće je objasniti manjom količinom izdvojenog vodonika na katodi tokom elektroforetskog taloženja. | sr |
