Abstract

1,130,358. Treating electrolytically chromated metals. TOYO KOHAN CO. Ltd. Oct. 20,1965 [Nov. 12, 1964], No. 44487/65. Heading C7B. A metal is electrolytically chromated as a cathode to form a hydrated chromium oxide film thereon and the film is improved by rinsing the chromated metal with water and immediately immersing it in an aqueous solution or dispersion containing from 1 to 50 g/l of at least one cationic surface active'agent selected from the group consisting of : - 1) Aliphatic primary amine acetates having a formula RNH 3 COOCH 3 wherein R is an aliphatic hydrocarbon group having 8-18 carbon atoms. 2) Quaternary ammonium salts having a formula [RRR'R"N]X where R is an alkyl group having 1-5 carbon atoms, R' is selected from the group consisting of saturated and unsaturated aliphatic hydrocarbon groups having 1-22 carbon atoms, benzyl group and alkanol group having 1-5 carbon atoms, R" is an aliphatic hydrocarbon group having 8-22 carbon atoms and X is a halogen or hydroxyl group and also their derivatives having at least one ester, ether or amide bond. 3) Pyridinium salts having a formula where R is an aliphatic hydrocarbon group having 12-18 carbon atoms and X is a halogen atom and their derivatives having at least one ester, ether or amide bond. 4) Picolinium salts having a formula where R, X and their derivatives having at least one ester, ether or amide bond. 5)Polyoxyethylene alkyl amines having a formula of where R is an aliphatic hydrocarbon group having 8-18 carbon atoms and m are 8-18. 6)Polycondensation products obtained by the reaction of dicyanodiamides and HCHO, e.g. S. of dicyanodiamides being dicyanodiamide dicyanodiamidine, guanidine and diguanide. The cationic surface active agent solution may be used at 30- 70‹ C. and the immersion time in the aqueous solution may be 1-60 secs. The metal to be treated may have a surface selected from Fe, seel, Al, Cr, Ni, Zn, Sn, Cd, Mg, Cu, Ti and alloys based on any of these metals. After treatment, the metal may be coated with a modified alkyd or modified epoxy lacquer. In the electrolytic chromating of the metal as a cathode a Pb/Sb anode may be employed. Electrolytic chromating baths are specified in Examples 1) H 2 CrO 4 +H 2 SO 4 +H 2 SiF 6 3) H 2 CrO 4 + phenol-2, 4-disulphonic acid. 4) Na 2 Cr 2 O 7 + chromium sulphate +(NH 4 ) 2 SO 4 7) Na 2 Cr 2 O 7 + H 2 SO 4 .
