The optimal parameters of the anodic oxidation of aluminium in orthophosphoric acid solution was determined. In the pores of the obtained Al 2 O 3 membranes with the ordered nanometric structure Co-Fe alloys were electrodeposited. The Al 2 O 3 membranes were obtained in the two-stage anodic oxidation of aluminium in the 0.17 M H 3 PO 4 solution in the temperature 1 0 C and at the electrolysis voltage 180 V. The influence of the anodizing process parameters on the thickness of oxide films and the diameter of pores and the distance between them in the alumina membranes were determined.The electrodeposition of Co-Fe alloys was carried out from sulphate baths containing sulphates (VI) of copper (II) and cobalt (II) of different composition, in potentiostatic conditions. The optimal electrolysis conditions were determined, where the cathodic deposits of the best quality were obtained. The conditions are: the electrolyte composition: 0.3 M Fe; 0.5 M Co; pH = 3, the potential: -0.760 V (vs. SHE 1) ). Keywords: anodic oxidation of aluminium, nanowires, Co-Fe alloyOkreślono optymalne parametry anodowego utleniania aluminium w roztworze kwasu ortofosforowego W porach uzyskanych membran Al 2 O 3 , o uporządkowanej strukturze nanometrycznej, osadzano elektrolitycznie stopy Co-Fe. Membrany Al 2 O 3 otrzymywano w procesie dwuetapowego utleniania aluminium w roztworze 0,17 M H 3 PO 4 , w temperaturze 1• C, przy napięciu elektrolizy 180 V. Zbadano wpływ parametrów anodowania na grubość warstewek tlenkowych, średnicę porów i odległości między nimi w membranach tlenku glinu.Elektroosadzanie stopów Co-Fe prowadzono z roztworów siarczanowych (VI) zawierających jony miedzi (II) i kobaltu (II) o różnym składzie, w warunkach potencjostatycznych. Określono optymalne warunki elektrolizy, w których otrzymano osady katodowe najlepszej jakości. A mianowicie: skład elektrolitu : 0,3 M Fe; 0,5 M Co; pH = 3, potentiał: −0,760 V (wzgl. SEW).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
