Abstract

1419613 Electro-depositing metal LEARONAL Inc 13 June 1974 26189/74 Heading C7B Bright metal or alloy, e.g. Fe, Co, Ni, Zn, Ag, Cu, Cd, Sn, Cu - Ni, Cu - Zn or yellow or white brass, is electro-deposited from a cyanide-free aqueous solution containing a metal chelate formed of a water-soluble phosphonate chelating agent combined with ions of the metal(s) to be electrodeposited and an oxidizing agent, preferably 0.01 to 5 g/l, selected from peroxides (including organic peracids and salts of inorganic peracids that possess -0-0), chlorites, perchlorates, hypochlorites, potassium periodate, permanganates and sulphoxides. Examples of oxidizing agent are (chloro) perbenzoic acid, dimethyl sulphoxide, peracetic or permaleic acid: H 2 O 2 ; potassium perchlorate, periodate, permanganate, peroxymonosulphate, perborate or peroxydiphosphate; sodium perborate, chlorite or hypochlorite; ammonium persulphate. Examples of the phosphonate chelating agent are diethylene triamine pentamethylphosphonic acid, triethylene tetraamine hexamethylphosphonic acid, tetraethylene pentaamine heptamethylphosphonic acid, hexamethylene or ethylene diamine tetramethyl-phosphonic acid, aminoethyl ethanolamine or piperazine trimethylphosphonic acid, diamino pyridine tetramethylphosphonic acid, and hydrazine tetramethylphosphonic acid, and their alkali metal or ammonium salts; suitable chelating agents are organophosphorus ligands of the formula Z (PO 3 M 2 )n as described in U.S. Patent Nos. 3475293 and 3833486. The solution may also contain as brightening agent a soluble salt of Tl, Pb, Cd, As, Sb, or Bi (e.g. Na Bi tartrate); Na selenite or tellurite; or an amino acid, e.g. lysine or cysteine HCl, alanine, methionine, glycine or 1-tyrosine. Examples of plating metal salts in the solution are CuSO 4 ,Na 2 ZnO 2 ,NiSO 4 ; the carbonate, hydroxide or oxide of the plating metal may be added to react with the chelate, the pH being adjusted with NaOH, KOH, NH 4 OH or alkali metal carbonate.
