Abstract
To obtain cathodes for the electrolysis of sodium chloride, by electroless Ni-S-P alloy plating on soft iron plates, deposits containing various levels of sulfur content were prepared using ammoniacal alkaline citrate baths containing sodium hypophophate as the reducing agent and trace additives including sulfur.The following results were obtained:1) Adding 10ppm sodium thiosulfate to the plating bath made it possible to prepare deposits containing up to 5% sulfur.2) In baths not containing sodium citrate, the deposition rate increased, but the sulfur content in the deposits decreased.3) When the thickness of deposits increased, their sulfur content decreased and deposition stopped.
