FIELD: metallurgy.
SUBSTANCE: metal coating is applied by electrochemical deposition from electrolyte whereto additive of polyphosphate or the mix of polyphosphates are added in amount of 0.1-450 g per one liter of electrolyte. Note here that the metal is selected from the group of noble metals including silver and metal of platinum group.
EFFECT: higher adhesion of coatings, wear resistance, antirust properties.
