Abstract

Tailorable deposition was carried out by varying the Sn:Ni molar ratio of a pyrophosphate bath to adjust the deposition rate as well as the phase composition, morphology and corrosion resistance of the as-deposited SnNi alloy. The nickel content of the resultant SnNi alloy decreases gradually from 50 wt% to 28 wt% when the Sn:Ni molar ratio of electrolytes increases from 0.2 to 2.0 and remains reasonably constant at 31
