Oxidation Protective

August 9, 2005

The Secretary of the United States
Air Force has obtained a patent for a
method for enhancing the oxidation
resistance of substrates fabricated from
carbon-carbon and metals and alloys
which have a minimal reaction with
molybdenum. It is comprised of depositing
a layer of molybdenum on the surface,
then depositing silicon on the
molybdenum layer under conditions
which cause the formation of an outer
layer of MoSi2, wherein said silicon is
deposited on the molybdenum layer by
placing said substrate with the molybdenum
deposit thereon in a container
vessel together with silicon powder and
a catalyst, evacuating said vessel and
heating the resulting assembly to a
temperature of approximately 800 to
900°C for two to 20 hours.
