Abstract

1,209,347. Electroless plating. TRANSMETALS CORP. Jan. 16, 1968 No. 2420/68. Heading C7F. An electroless bath contains a water soluble metal salt, an acid and a carbohydrate in a concentration of at least 50 g/l. The plating metal may be Al, Cd, Co, Cu, Pb, Ag, Au, Sn, Zn, Mg, Li, Mn, Sr, and Ni, and the salt may be a nitrate, sulphate, chloride or gluconate. The substrate may be steel, Ni, Sn, Cu, brass, Al, Zn, Pb, Au, Be, Ti, Pt, ceramic or plastics, e.g. polyester or polystyrene. When plating Be with Ag, a coating of Cu may be applied first. The acid may be acetic, citric, tartaric, lactic, gluconic, formic, maleic, oxalic, adipic, sebacic, palmitic, stearic, lauric, carbolic, salicylic, boric, phosphoric, sulphuric, hydrochloric or nitric. The carbohydrate may be glycerose, dextrose, xylose, ribose, glucose, mannose, galactose, fructose, lactose, maltose, sucrose, dextrin, inulin, starches or cellulose esters, e.g. acetate. The bath may also contain phytol or guanylic acid. A sensitizing bath containing gluconic acid, a carbohydrate and a wetting agent e.g. ammonium alkyl sulphate, sodium alkyl aryl sulphate or amine salts of dodecyl benzine sulphinic and phosphinic acids may be used.
