摘要：1481564 Electro-depositing Ni-Fe alloy OXY METAL INDUSTRIES CORP 17 July1974 [1 April 1974] 31732/74 Heading C7B Bright Ni-Fe alloy, suitable for receiving asubsequent Cr electro-plate, is deposited from an aqueous acidic bath comprising Ni andFe ions (Fe2+ with or without Fe3+) together with a primary Ni brightener, a metalcomplexing agent, a reaction product of a polyamine with an alkylating or sulphonatingagent and optionally an acetylenic secondary Ni brightener. The primary brightener maybe a sulpho-oxygen compound such as saccharine, naphthalene trisulphonic acid,sulphobenzaldehyde, dibenzenesulphonamide, Na alkyl sulphonate, a benzenesulphinate, vinyl sulphonate, #-styrene sulphonate or a cyano C 1-4 - alkyl sulphonate.The complexing agent may be a hydroxy or'amino carboxylic acid e.g. citric, tartaric orgluconic (others listed). The polyamine may be polyethyleneimine of M.W. 300-24000reacted with e.g. propane sultone, sulphamic acid or propargyl epichlorhydrin (otherreagents listed). Many listed acetylenic compounds include 2-propynoxy ethanol, 2-hydroxy-3-propynoxy-1-propane sulphonate, 1-propynoxy-3-chloro-2-propanol and 1-propynoxy-2-propanol. Conventional Fe and Ni sources are used. A pH buffer e.g. B(OH)3or Na acetate may be added to pH 2À5-5À5. Metallic or plastics substrates may be

plated, the latter after being rendered conductive with Ni or Cu.
