Improved silver cyanide plating baths : laboratory development / W. Dingley, J. Bednar and R.R. Rogers, Extraction Metallurgy Division. : M38-8/87E-PDF
"Improved silver plating results were obtained during laboratory experiments in which the bath constituents were related to one another as follows: (1) Y = 0.374 + 0.768X – 0.178X2 where Y = OH – normality, and X = “free” CN – normality; (2) total NaCN normality/Ag normality is between 6.1 and 8.1 (the exact value depending on the bath composition). The advantages of these improved silver plating baths include: low rate of cyanide consumption and carbonate formation; high current efficiency and low cell voltage when operating at comparatively high cathode current density; deposition of uniform fine-grained deposits in the absence of brighteners; insolubility of the silver anodes in the plating bath when the latter is not in use; absence of silver deposition on unconnected steel cathodes immersed in the plating bath; ability to plate satisfactory silver deposits directly on steel; ability to plate high strength steels, such as Types 1062 and 4037, directly with silver without embrittling the steels"--Abstract, p. 1129.
