Abstract

1,154,023. Electrolytically coating ferrous members with aluminium oxide. RANSBURG ELECTRO-COATING CORP. May 10, 1966 [May 10, 1965], No.20600/66. Heading C7B. A ferrous member is coated with aluminium oxide by anodic deposition from an aqueous bath containing dissolved monoaluminium phosphate using D.C. and a consumable aluminium cathode, the coated member then being removed from the bath and dried at elevated temperature, yielding an insulating coating. Preferably the bath is of pH 1 to 5 and the monoaluminium phosphate may form 16 to 50% by weight of the aqueous solution. Typically a silicon steel plate is degreased with trichlorethylene and is then immersed in a bath at 70‹ F. containing by weight 1 part monoaluminium phosphate to 2 parts water, giving a pH of 1À5 and coating is effected by applying 8 volts for five minutes. The anodic deposit which is gelatinous may be baked at 800‹ F. for 45 seconds, the coated member preferably being slowly withdrawn from the bath while current is still flowing. Improved electrical qualities are obtained if the bath contains about 4g/1 NaF.
