Method of controlling surface of aluminum alloy outer panel or component for power generator or vehicle

摘要

The present invention relates to a method for modifying the surface of an aluminum alloy shell or parts of a generator or vehicle, and a method of hydrophobically treating the surface of an aluminum alloy shell or parts of any one of the generator, automobile, ship, train, and aircraft of the present invention. The three-dimensional anodized film structure is controlled by implementing the pore shape, diameter, and density of the anodized aluminum layer formed on the surface of the aluminum alloy in various forms such as pillar-on-pores through control of silver anodization voltage and time. It has an economic effect of manufacturing an aluminum alloy in a short time at low cost, and the aluminum alloy with a controlled anodized film structure manufactured by the above method has excellent superhydrophobicity, corrosion resistance, and aesthetic function, so it is a generator, automobile, ship, or aircraft. It can be used as the outer plate or parts of
