HIGH-TEMPERATURE OXIDATION PROTECTIVE COATINGS FOR VANADIUM-BASE ALLOYS

Abstract

The objective is the development of oxidation protective coatings for vanadium-base alloys for use at 1800 to 2500 F. The effect of the pack siliconizing process on the mechanical properties of .020 inch thick sheet of V- 60 w/o Cb - 1 w/o Ti is being studied. Samples are being evaluated before and after various high temperature exposures. Development of an oxidation resistant slurry or liquid cementation type coating for V-60 w/o Cb - 1 w/o Ti is progressing. Five slurry compositions containing tin, silicon, silver, copper, aluminum, and columbium were investigated, and several of these showed good coverage, even at corners and edges.
