Abstract: A coated article, comprising an article having at least one surface having disposed thereupon an oxidation resistant coating comprising at least two constituents to form a composition, a first constituent comprising at least one thermal expansion component comprising at least about 10% by volume to up to about 99% by volume of the composition, a second constituent comprising at least one oxygen scavenger comprising at least about 1% by volume to up to about 90% by volume of the composition.

Abstract: A heat exchanger panel assembly includes two panels, one with milled channels approximately in cross-section which flow coolant, and the other a close-out nominally flat panel which is bonded to the tops of the ribs of the milled channel with a thin interlayer of a transient liquid phase (TLP) bonding agent foil as the bonding interface. The method of manufacture provides transient liquid phase bonding coupled with vacuum compression. The bonding is accomplished by vacuum compression at elevated temperature in a furnace in which a vacuum is impressed on the channels while high pressure is forced on the panel exterior which forces all bonding interfaces into intimate contact.
