Abstract

1,151,460. Electro-depositing tin-lead alloy. M. KANAI. Oct. 9, 1967, No.46019/67. Heading C7B. A bright Sn-Pb alloy is electro-plated on to an article immersed as cathode in a bath comprising a stannous and a lead salt e.g. fluoborate, and the reaction product of acetaldehyde and O-toluidine as a brightening agent. The bath may also contain an ether type non-ionic surface active agent, e.g. polyethylene glycol nonyl phenyl ether, to disperse the brightening agent, and hydroquinone as an antioxidant. Free fluoboric and boric acids, formaldehyde and #-naphthol may also be present. The reaction product is preferably extracted with isopropyl alcohol for adding to the bath. The surfaceactive agent may be obtained by adding ethylene oxide to nonyl phenol or isocytyl alcohol. The article may be slowly moved while plating.
