Abstract

This program was started with a survey to determine potential coating materials for protecting tantalum alloys from oxidation and contamination at high temperatures. This survey and initial coating studies resulted in major emphasis being directed toward silicide-based coatings. Straight silicide coatings and modifications with aluminum, boron, chromium, manganese, molybdenum, titanium, and vanadium were applied to tantalum, Ta-10W, Ta-10Hf-5W, and Ta-30Cb-5V by pack-cementation techniques. These coated materials were evaluated primarily by statis, cyclic, and defect oxidation studies in the temperature range of 1200 to 2700 F. Less extensive studies were conducted on tantalum coated with aluminum, chromium, hafnium, titanium, zinc, and Al2O3.
