The U.S. Air Force has identified a need for advanced protective coating systems for its aging aircraft. Durable (30+years) chromate-free coatings are needed to extend the retirement dates of the aging aircraft. A chromate-free coating is needed to avoid the costs of handling of chromate containing hazardous wastes. Unfortunately, in a recent study of chromate-free conversion coatings, all the ...

Naval transports and ordinance are currently coated to prevent corrosion and other destructive weathering phenomena. These coatings have a limited life-span as adhesion is compromised when they degrade on exposure to light, moisture, abrasive wind and wear. Special properties necessary for naval coatings include non-skid characteristics, corrosion and fire resistance, high mechanical strength an ...

Aircraft designed for hypersonic flight use fuel to cool the ramjet/scramjet propulsion system. Sensible heating and endothermic reactions are used to provide cooling and may produce fuel temperatures that exceed 1200 degrees F. At these temperatures carbonaceous deposits (coke) form. These deposits can inhibit fuel flow, reduce heat transfer, and create hot spots. Coke deposits are known to ...
