ABS>A wide range of coating techniques is being investigated for the oxidation protection of vanadium alloys at temperatares above 1800 deg F. Coatings of Zn, Zn--10 wt.% Al, Zn-10 wt.% Sn, and MgNi2 were prepared to explore selfhealing properties on V--5 wt.% Ti--20 wt.% Cb and V-60 wt.% Cb. Diffusion- type coatings included the pack-cementation of silicon on V--5 wt.% Ti--20 wt.% Cb. After exposure to air for 28 hours at 1800 deg F and 4 hours at 2000 deg F, the coatings were intact, but small weight losses indicated the loss of V/sub 2/O/ sub 5/. Other approaches currently under study include roll-bonding of Fe-- Cr-- Al, the liquid-phase sintering of a Cr-- Au alloy, and flame-sprayed barium titanate. (auth)
