Straight silicide coatings and modifications with aluminum, boron, chromium, manganese, molybdenum, titanium, and vanadium were applied to tantalum, Ta-10W, Ta-V, Ta-10Hf-5W, and Ta-30Nb-5V by pack-cementation techniques. These coated materials were evaluated primarily. by static, cyclic, and defect oxidation studies in the temperature range 1200 to 2700 deg F. Less extensive studies were conducted on tantalum coated with aluminum, chromium, hafnium, titanium, zinc, and Al/sub 2/O/sub 3/. (auth)
