Abstract:A lum inium alloy was anodized by a constant current density, and the oxide film obtained was
pact than that obtained by constant voltage. Then the oxide film was coated with a film of B is
phenol A epoxy resin. After this, the epoxy resin film was heat solidified at 200℃~230℃ for a long
time. The multip le film s obtained through this method exhibited good electric insulativity. A lso, the corro
sion resistance was greatl
