Abstract

1412929 Electrolytically treating surfaceoxidized aluminium KANSAI PAINT CO Ltd 25 June 1974 [4 July 1973 23 July 1973 15 Nov 1973 (2) 19 Nov 1973] 28037/74 Heading C7B Al or an alloy thereof is surface oxidized using steam or hot-water and is subsequently treated electrolytically for at least 5 seconds in an aqueous bath containing at least one water-soluble salt of silicic, boric, phosphoric, permanganic, vanadic, tungstic, molybdic or stannic acid. The oxidation may be effected in the presence of ammonia or an anine e.g. mono-, di- or triethanolamine or dimethylethanolamine. An extensive list of salts is given and treatment may be in a mixed salt bath or in a succession of baths containing the same or a different salt. The following are used in examples; Na 2 O.2SiO 2 , K 2 O.3SiO 2 , NaBO 2 , NaPO 3 , Al(H 2 PO 4 ) 3 , KMnO 4 , Ca(MnO 4 ) 2 .4H 2 O, NH 4 VO 3 , KVO 3 , K 2 WO 4 , K 2 W 4 O 13 , (NHa) 2 WO 4 , K 2 MoO 4 , (NH 4 ) 6 Mo 7 O 24 and K 2 SnO 3 .3H 2 O. A water-soluble salt of chromic acid may also be present. Salt concentrations from 0.1% to saturation are useful using 5-200V A.C. or 5.300V D.C. Alloys treated may contain SiŒMg, Mn or Mg. The substrate may be pretreated successively in HNO 3 or H 2 SO 4 , NaOH and optionally HNO 3 again, and the final coating may be heated at 150-250‹C for hardening.
