THE EFFECT OF ARC PLASMA DEPOSITION ON THE STABILITY OF NON-METALLIC MATERIALS
Abstract
The oxides o Al, Cr, Zr Ce, Hf and mixtures of Zr and Nb; the carbides of Hf, Ta and Zr; the nitrides of Ti and Ta; and the boride of Zr can be sprayed on a graphite substrate without chemical or microstructure alteration; the operating conditions for the depositi n of these materials were determined. Properties usef l in design data: the coefficient of thermal expansion, density, compressive strengths, electrical resistance and hardness were obtained. The resistance of the deposited coatings to a 5000 F, high velocity, air blast was determined as well as the static oxidation behavior. Alumina, chromia and zirconium boride conferred resistance to a graphite substrate in the blast test. The carbide and nitride did not withstand the oxidation erosion test. (Author)
