Abstract:
Identifiers Pack cementation.A survey was made to determine potential coating materials for protecting Ta alloys from oxidation and contamination at high temperatures. This survey and initial coating studies resulted in major emphasis being directed toward silicidebase coatings. Straight silicide coatings and modifications with Al, B, Cr, Mn, Mo, Ti, and V were applied to Ta, Ta-10W, Ta-10Hf-5W, and Ta-30Cb-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 F. Less extensive studies were conducted on Ta coated with Al, Cr, Hf, Ti, Zn, and Al2O3. Author
