CHEMICALLY BONDED ALUMINUM COATING FOR CARBON VIA MONOCARBIDES

摘要

CHEMICALLY BONDED ALUMINUM COATING FOR CARBON VIA MONOCARBIDES An aluminum coated carbon article or composite, and process therefor having aluminum chemically bonded to carbon via an interface of a metal monocarbide formed in situ when an intermetallic phase comprising aluminum and a metal capable of reacting with carbon to form a metal carbide is reduced by carbon to aluminum and a metal carbide, the metal selected from the group consisting of tantalum, titanium and hafnium.
