[en] Ag_-Ni_1-x film alloys on Cu substrates are grown by electrodeposition in unproton-dipolar solution of Ag and Ni salts. The films containing from 0 % to 95 % Ni possible are grown by changing the electrolyte compound and current density. The dependence of the grain size from the nickel content in Ag-Ni is investigated. From X-ray spectroscopy investigation the Ag-Ni films with the content Ni more than 15% the grain size decrease from 50 nm to 3-5 nm. By the electron transition microscopy it was shown that the film of Ag/Ni-50/50 composition is the mechanical intermixture of grains Ag and Ni with the size 3 nm. (Authors)
