    Abstract: A method for selectively removing one or more coatings from the surface of a substrate is described. The coating is treated with an aqueous composition which includes an acid of the formula H x AF 6 , or precursors to such an acid. In that formula, A is Si, Ge, Ti, Zr, Al, and Ga; and x is 1-6. The acid is often H 2 SiF 6 . The composition may sometimes include at least one additional acid, such as phosphoric acid. The coating being removed is often an aluminide coating or an MCrAl(X)-type material. The substrate is usually a polymer or a metal, such as a superalloy.

    Abstract: A gas turbine engine (20, 80) has a compressor section (24) including a lower pressure compressor (44, 94) and a higher pressure compressor (52, 100), and a turbine section (28). A core engine housing (90) surrounds the compressor section (24) and the turbine section (28). An outer intermediate housing wall defines an internal chamber (88) between the core housing (90) and the outer intermediate housing (86). A fan rotor (42, 84) and a fan casing (82) surround the fan rotor (42, 84) to define a bypass duct (B) between the fan case (82) and the outer intermediate housing (86). A heat exchanger (108) is mounted in the internal chamber (88) and receives high pressure air for cooling the high pressure air and delivering the high pressure air into the core engine housing (90) to be utilized as cooling air for a component. Air from the lower pressure compressor (44, 94) is utilized to cool the higher pressure air in the heat exchanger (108).
