ducing a stable contact angle with water of not more than 15”.

Method for Preparing Aluminum Alloy Fasteners U.S.Patent 5614,037. Mar.25, 1997 S.G. Keener, assignor to McDonnell Douglas Corp., Long Beach, Calif. A method for preparing an aluminumalloy article comprising providing a 7050 aluminum-alloy fastener; providing a corrosion-resistant, curable organic coating material comprising a phenolic resin and an organic solvent; applying the material; and heating to a temperature sufficient to simultaneously heat-treat the aluminum-alloy fastener and cure the organic coating.

A method of providing a semiconductor device with an inorganic electrically insulative layer, comprising exposing the semiconductor device to a phosphoric acid solution to form a phosphate coating on the exposed semiconductor surfaces, and not on the end terminations, and coating the semiconductor device with an electrically conductive metal in a process in which the device is electrically charged and submerged in a plating solution, the metal being formed on the end terminations and not on the phosphate coating because the phosphate coating is not electrically conductive.
