INVESTIGATION OF FEASIBILITY OF UTILIZING AVAILABLE HEAT RESISTANT MATERIALS FOR HYPERSONIC LEADING EDGE APPLICATIONS. VOLUME 7-OXIDATION RESISTANCE OF BARE AND COATED MOLYBDENUM ALLOY AND GRAPHITE

Abstract

facilities, Test methods, Gliders, Materials, Aerodynamic heating, Plasma jets, Heating, Ceramic coatings. Results are presented of oxidation resistance tests of bare and coated 0.5% Ti alloy of Mo and ATJ graphite. Chromalloy W-2 and Durak MG coatings were evaluated on the Mo alloy while the ATJ graphite was coated by the National Carbon Company's siliconizing process. Tests were conducted in 5 different facilities including 3 arc plasma jets at temperatures from 2000 to 3400F and times from 1 min to 4 hr. Both uncoated materials reacted exothermically under oxidizing conditions. A high degree of failures were encountered on all coated specimens.
