Abstract

1363041 Forming oxide coatings J N TUTTLE Inc 7 Aug 1972 [10 Aug 1971] 36717/72 Heading C7U A process for forming an oxide coating on an Al or Al alloy surface, comprises contacting the surface with an aqueous alkaline solution of a ferricyanide salt, preferably an alkali metal or alkaline earth ferricyanide, e.g. K 3 Fe(CN) 6 . The pH of the solution is maintained between 10 and 13 by a pH adjuster, e.g. K 2 CO 3 , NaOH, trisodium phosphate, and an inhibitor may also be added, e.g. trisodium or tripotassium phosphate. The process is carried out between 70‹-100‹F, and the treated surface may be subsequently dyed and sealed. Prior to treatment, the surface may be degreased, etched, desmutted, and rinsed.
