Abstract

The processes of electrodeposition of tin–nickel alloys on 08kp steel from oxalate–ammonium electrolytes and the physicochemical properties of the coatings were investigated. It is shown that the electrodeposition proceeds with high polarization, in contrast to the process of deposition of tin–nickel alloys from a chloride–fluoride electrolyte. The highest corrosion rate (26 μA/cm2) corresponds to a sample with a coating obtained from the chloride–fluoride electrolyte. Low corrosion rate is observed for coatings of tin–nickel alloys with a low nickel content deposited from oxalate–ammonium electrolytes with the addition of the OS-20 preparation (1.2–5 μA/cm2). The influence of the ratio of alloy components on the chemical composition and microstructure of the coatings is demonstrated.
