Descrição: The final annual report of a three-year program concerning basic factors controlling the oxidation behavior of high temperature protective coatings for graphite is presented. The work includes: the permeabiltiy of Al2O3, ZrO2 in contact with ZrB2, and ThO2 in contact with ZrB2 to oxygen; the iridium-carbon eutectic temperature; the thermal expansion of ZrB2, HfB2, and various composites of ZrB2 and HfB2 with one of the rare earth hexaborides, CeB6, YB6, or LaB6; the deposition of ZrB2 on graphite via the decomposition of Zr(BH4)4; the diffusion of carbon in zirconium monocarbide and zirconium diboride; a review of the literature concerning the vapor species in the iridium-oxygen system and mass spectrometric studies involving the dissociation of CaZrO3 at temperatures to 1600 C and HfSiO4 at temperatures to 2000 C.
