Electrocatalytically active Ni-Re binary alloys electrodeposited with superimposed magnetic field

The aim of this work was to obtain Ni-Re binary alloy by a simple method of electrodeposition. Nickel - rhenium alloys have been deposited from nickel sulfamate and ammonium perrhenate electrolyte with citrate-anion additives. The effect of magnetic field superimposed during electrodeposition was studied. The impacts of that parameter on hydrogen evolution process for obtained Ni-Re alloys were examined. The deposited layers were determined by optical and scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF).

Celem pracy było uzyskanie stopów Ni-Re metoda osadzania elektrolitycznego. Stop niklowo renowy osadzano z elektrolitu zawierającego sulfaminian niklu oraz nadrenian amonu. Stosowano bufor cytrynianowy. Badano wpływ przyłożonego zewnętrznego pola magnetycznego podczas osadzania stopu na wydzielanie wodoru na tak uzyskanym stopie. Badano osadzone warstewki stopowe za pomocą mikroskopu optycznego oraz mikroskopu skaningowego i metodami XRD oraz XRF.
