The phase composition of Zn-Ni alloy films electrodeposited from a slightly alkaline polyligand electrolyte was analyzed by anodic voltammetry method. The mechanism of films anodic dissolution in alkaline ammonia-glycinate solution not containing metal ions is proposed. The main peaks correspond to the zinc dissolution from пЃЁ-phase and from пЃ§-phase of the initial film and the nickel-enriched phase formed during the film dissolution. The nickel content in the nickel-enriched phase is determined, as well as nickel and пЃ§-phase content in the original film, depending on the ratio of metal ion concentrations in the electrolyte at various ratios of glycine and ammonia concentration. It is shown that films in a wide range of these ratios ([Ni2+]:[Zn2+]В пЂЅВ (2-5):1 and [Gly-]:[NH3(NH4+)]В пЂЅВ (2-9):5) contain mainly пЃ§-phase with nickel content in the range of 15.8-18.2%.
