Abstract
A method for the treatment of aluminum surfaces to provide them with a corrosion resistant, hydrophilic coating. The aluminum surfaces are first provided with a corrosion-resistant film and, thereafter, a coating of fine silica particles is applied to the corrosion resistant film. Suitable corrosion resistant films which may be used are anodized films, boehmite films, chromated films and organic resin films. The coated aluminum surfaces produced by this method are found to have particular application for aluminum heat exchangers.
