HIGH-TEMPERATURE OXIDATION PROTECTIVE COATINGS FOR VANADIUM-BASE ALLOYS

Abstract

A wide range of coating techniques is being investigated for the oxidation protection of vanadium alloys at temperatures above 1800 F. Coatings of Zn, Zn-10w/o Al, Zn-10w/o Sn, and MgNi2 were prepared to explore self-healing properties on V-5w/o Ti-20w/o Cb and V-60w/o Cb. Diffusion-type coatings included the pack-cementation of silicon on V-5w/o Ti-20w/o Cb. After exposure to air for 28 hours at 1800 F and 4 hours at 2000 F, the coatings were intact, but small weight losses indicated the loss of V2O5. Other approaches currently under study include roll-bonding of Fe-Cr-Al, the liquidphase sintering of a Cr-Au alloy, and flamesprayed barium titanate. (Author)
