KINETIC AND AERODYNAMIC ASPECTS OF THE OXIDATION OF MATERIALS BY PARTIALLY DISSOCIATED GASES
Abstract
A synopsis is presented of the most significant results of a three- year research program carried out on the oxidation kinetics of refractory materials in dissociated gases. Microwave-discharge fast flow system techniques, coupled with electrical resistance heating and monitoring of the reacting specimens were used throughout. Experimental results are included for the attack of (a) polycrystalline molybdenum, tungsten, graphite, iridium and vitreous boron by atomic oxygen, (b) polycrystalline molybdenum and nickel by atomic chlorine, and (c) polycrystalline molybdenum by hydroxyl radicals. Reactant (O, Cl, and OH) partial pressures were of the order of 0.001 to 0.05 and surface temperatures were within the range 400 to 2600K. A chronological list is provided of the seven publications and eleven reports describing these results and the underlying methods in greater detail.
