Abstract

PURPOSE: To increase the coating film thickness of the oxidation film and improve the corrosion resistance, by subjecting the oxide film on the surface of aluminium to the three-stage sealing processing consisting of soaking into the aqueous solution of a metal salt, an ammonium derivative, and so on, soaking into hot water, and electrodeposition coating of the coating material.
CONSTITUTION: An anodic oxidation film is formed on aluminium or an aluminium alloy, and it is soaked into the aqueous solution of the known sealing agent such as a metal salt, an ammonium derivative, an amine compound, an alkali hydroxide, and a boron compound as the first sealing processing. Next, it is soaked into heated water as the second sealing processing, and further, it is subjected to electrodeposition coating in the aqueous solution of a thermosetting resin or the electrodeposition coating bath of emulsion as the third sealing processing. After that, the coating material is hardened in the heating furnace and so on.
