Abstract
A process includes means for depositing an anti-corrosion coating filled with liquid oil on an aluminum substrate. Aluminum is anodized and then treated with a thin hydrophobic sub-coating. The pores created through anodization are then impregnated with liquid oil. Oil penetration is maximized and residual air is minimized by first filling the pores with a filling solution, replacing the filling solution with an exchange fluid, and then replacing the exchange fluid with perfluorinated oil. The oil gives the surface coating anti-wetting properties and self-healing properties, thereby protecting the aluminum substrate underneath from corrosion.
