Electrodeposition of tin–nickel alloys from oxalate–sulfate and fluoride–chloride electrolytes

Аннотация

The processes of electrodeposition of tin–nickel alloys from sulfate–oxalate and fluoride–chloride electrolytes are investigated. Oxalate electrolytes for the deposition of the tin–nickel alloy have a high throwing power in comparison with that of the fluoride–chloride electrolyte. Increasing the polarization in the electrodeposition of alloys from an oxalate electrolyte provides an increase in the microhardness and corrosion resistance of coatings.
