1. A method for improving adhesion, the method comprising the steps of:
providing a base substrate; and
achieving a desired material property by:
immersing the base substrate in a silane solution;
applying a deionized cold-water rinse to the base substrate; and
drying the base substrate at a predetermined temperature;
wherein the desired material property includes achieving an elemental ratio of aluminum to magnesium between approximately 3 to 17 of the base substrate, an elemental ratio of oxygen to carbon between 3 to 11 of the base substrate, and a contact angle of less than 30 degrees formed on the base substrate such that upon application, to the base substrate, of an adhesive material an increased adhesive bond of a predetermined strength is attained.
