Abstract: Electrolyte for electroplating of chromium based coatingThe electrolyte consists of:a liquid component, containing hexavalent ions of chromiuma metal component, chosen from the group II of the Periodical Tablea particulate solid component, comprising a compound of refractory metal of the groups IVb, Vb of VIb of the Periodical Table.Chromium based coating is electroplated from an electrolytic bath, containing said electrolyte. The coating consists of a matrix, presented by solid solution of chromium with said metal component and of distributed within said matrix particles of a solid component. The coating has improved wear resistance, corrosion resistance and plasticity and it can be deposited both on metallic and non-metallic substrates.
