Glycine can inhibit the reduction of Ni2+ ions but promote the reduction of Mn2+ ions.
Glycine changes the mode of Ni–Mn film growth from Volmer–Weber mode into Stranski–Krastanov mode.
Glycine promotes the dissolution of both Ni and Mn deposits in the ChCl–urea ionic liquids.
The Mn content in the Ni–Mn film depends on the concentration of glycine and current density.
The Ni–Mn film with 3.1 at.% Mn content exhibits better corrosion resistance than pure Ni film.
