Title: HIGH TEMPERATURE OXIDATION RESISTANT COATINGS FOR TANTALUM BASE ALLOYS. First Quarterly Progress Report, November 1, 1961-January 31, 1962

Abstract

The protective Sn-Al system was investigated in the 15 to 50 wt% Al range in attempts to optimize coating compositlon for refractory metals. Furnace teat weight galns were used to study coating on Ta, Ta-l0 W, Ta-l0 Hf-5W, Cb, Mo, and W at 2000 and 2500 deg F and on Ta-10 W at 2800 deg F. Further studies were performed at 3000 deg F using oxyacetylene torch and resistance heating technlques. Slgnlficant effects were related to coating composition, coating thickness, and sample size and geometry. Modification in coatlng additives gave promislng improvements in coating practicallty and oxldation resistance. Attempts were made to develop a similar diluent system for beryllide coatings. Poor results were obtained with Sn, Cu, and Si but the Ag-Le system looked promising. (auth)
