Electrodeposition of nickel
TL;DR: It has been found that certain unsaturated aliphatic sulfonic acids, such as CH2 C C-CH2SO3H, are excellent when used in acidic nickel plating baths in making it possible to obtain lustrous ductile nickel plate over a very wide plating range as mentioned in this paper.
