Abstract

A process for chemically plating a metallic or non-metallic surface with metal (e.g. Ni or Co from a hypophosphite bath) includes the steps of treating the surface to be plated with a solution of palladium chloride in a solvent comprising acetone with or without one or more additives, drying the surface and immersing it in a chemical plating bath. The additives may be H2O, CH3CHO and those esters of methyl, ethyl, butyl and propyl alcohols which are readily volatile at temperatures up to 200 DEG C., e.g. butyl formate, methyl salicylate, ethyl salicylate, ethyl benzoate, ethyl succinate, ethyl acetate, iso-propyl acetate and ethyl propionate. In dissolving the palladium chloride in the acetone, HCl may be employed which may subsequently be neutralized with NaHCO3. The surface of the article, before treatment with the solution, may be heated to a temperature up to 200 DEG C. and, after treatment, the drying may be at a slightly higher temperature. The treatment with the palladium chloride solution and any heating steps may be repeated. In the examples, the Ni or Co plating baths used are: a Ni bath maintained at 65-75 DEG C. of .Na4P2O7.50 gs./l .Ni sulphate.25 gs./l .NaH2PO2.25 gs./l .Na4OH.sufficient to maintain the ..pH at between 10 and 11 or a Co bath maintained at 95 DEG C. of .NaH2PO2.30 gs./l .Na citrate.20 gs./l .Co chloride.35 gs./l .NH4Cl.50 gs./l .NH4OH.sufficient to maintain ..the pH at 9 The articles a, the solvents s for the palladium chloride, the temperature t1 of the heating pretreatment and of the post-treatment t2 are as follows: 1) (a) nylon, melamine, epoxy resins, alkyd resins, polyester resins, polyformaldehydes and pyrophyllite; (s) acetone; (t1) 120-150 DEG C.; (t2) 200 DEG C. The article is sprayed with or immersed in the palladium chloride solution. 2) the same as for 1) except (s) is 60% methyl salicylate+40% acetone. 3) (a) phenolic plastic materials, asbestos, glass or ceramics; (s) acetone+n-butyl formate; (t1) 100 DEG C.; (t2) 120-150 DEG C. 4) (a) acrylic plastics; (s) acetone+acetalde-hyde; (t1) room temperature; (t2) 50-60 DEG C. The PdCl2-acetone solution may also be used on an active metal surface such as a Mg alloy.
