METHOD OF PLATING BY TIN Russian patent published in 2008 - IPC C25D3/32 

FIELD: metallurgy.

SUBSTANCE: method includes electrolyte preparation and tin settling, at that electrolyte is prepared by dissolution in distilled water 13-17 g/l of five-aquatic tin chloride (IV) in terms of metal and 140-160 g/l of lactic acid (80%) with electrolyte isolation during 24 hours at temperature 17-25°C for forming of lactate tin complex, and settling is implemented at cathode current density 0.5-1.0 A/dm², electrolyte temperature 20-28°C with usage of graphitic anode.

EFFECT: receiving of semiglittering, well-hitched to basis platings, increasing of outlet as current.
