dc.description.abstract | The effects of plating baths of different composition on the micro- structure and corrosion stability of Zn-Co alloy coatings were studied. Zn-Co alloys with the same Co content were deposited from chloride plating baths containing different amounts of Co2+, as well as from a sulphate-chloride plating bath. The surface morphology and crystallite size were investigated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The corrosion stability of the Zn-Co alloys was determined by following the change of the open circuit potential with time of immersion in a 3 % NaCl solution and by polarization measurements. The results showed a significant influence of the plating bath on the morphology and corrosion stability of the Zn-Co alloys. The surface of the alloy coatings deposited from the chloride baths were uniform and homogenous, whereas the deposit obtained from the sulphate-chloride bath was quite inhomogeneous. The corrosion stability of the homogenous Zn-Co deposits obtained by deposition from both chloride baths was higher than that of the deposit obtained from the sulphate-chloride bath. An increase in the Co content in the chloride-plating bath resulted in a reduction of the alloy crystallite size and it was shown that the alloy with the smaller crystallites of the two alloy deposits, although having the same chemical content, exhibited a lower corrosion rate. | en |
dc.description.abstract | U ovom radu je proučavan uticaj vrste rastvora za taloženje na mikrostrukturu i korozionu stabilnost prevlaka Zn-Co legura. Zn-Co legure sa istim sadržajem Co su elektrohemijski taložene iz hloridnih rastvora sa različitim sadržajem jona kobalta, kao i iz sulfatno-hloridnog rastvora. Morfologija površine prevlaka je ispitivana skenirajućom elektronskom mikroskopijom i mikroskopijom atomskih sila. Koroziona stabilnost prevlaka Zn-Co legura je određivana praćenjem promene potencijala otvorenog kola sa vremenom delovanja rastvora NaCl koncentracije 3%, kao i polarizacionim merenjima. Dobijeni rezultati su pokazali značajan uticaj vrste rastvora za taloženje na morfologiju i korozionu stabilnost prevlaka Zn-Co legura. Prevlake Zn-Co legura dobijene iz hloridnih rastvora su homogene, dok su prevlake dobijene iz sulfatno-hloridnog rastvora nehomogene. Koroziona stabilnost prevlaka legura dobijenih iz oba hloridna rastvora je veća u odnosu na stabilnost legura dobijenih iz sulfatno-hloridnog rastvora. Povećanjem sadržaja kobalta u hloridnom rastvoru za taloženje dobijaju se prevlake manjih kristalita i u radu je pokazano kako veličina kristalita utiče na korozionu stabilnost legura sa istim sadržajem kobalta. | sr |
