Electrodeposition of Tin-Nickel Alloy Plate from Chloride-Fluoride Electrolytes

Abstract

Tin and nickel can be codeposited in approximately equi‐atomic proportions from solutions containing stannous chloride, nickel chloride, and fluorides. The alloy deposits thus obtained are almost fully bright and are single phase, having a nickel arsenide type of structure. Below 300°C the deposits are quite stable, but on annealing at higher temperatures recrystallization takes place and a duplex structure of and results.
