HIGH TEMPERATURE PROTECTIVE COATINGS FOR GRAPHITE. Part 3
Abstract
Work presented includes: the oxidation kinetics of iridium and rhodium; the permeability of ZrSiO4, ZrO2, ThO2, Al2O3, and BeO to oxygen; an investigation of the iridium-carbon system by means of high temperature X-ray diffraction techniques and the deposition of iridium on graphite; the volatility of HfO2, ZrO2, ThO2, ThZrO4, SrZrO3, BaZrO3, ZrSiO4, and HfSiO4 in the presence of water vapor; the chemical kinetics of the carbothermic reduction of ZrO2, ThO2, HfO2, ThZrO4, and HfSiO4; the chemical kinetics of the reaction of ZrO2, HfO2, and ThO2 with ZrC, HfC, and ThC2, respectively; the chemical reactions of HfO2, ZrO2, and ThO2 with HfB2 and ZrB2; initial work on carbon diffusion through diborides and carbides; and the mechanical compatibility of components of multilayer oxidation protective coatings for graphite. The experimental results are discussed as to their practical implication to oxidation-protective coatings.
