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.
