Environmental Resistant Coatings for High Temperature Mo Silicide Alloys

Abstract

ln-situ reaction processing and kinetic biasing of diffusion paths in the pack cementation synthesis of robust coatings in the Mo-Si-B system has been demonstrated as an effective approach to achieve stable compatibility between coating layer/substrate alloy combinations. We have focused on a number of critical coating applications, namely (1) The capability of MoSiB coatings to suppress hot corrosion attack, (2) The oxidation resistance of MoSiB coatings in a water vapor environment (3) The use of MoSiB coatings for environmental protection of SiC/C Composites (4) The influence of minor alloying additions such as Al on the oxidation response of MoSiB coatings (5) Raman Spectroscopy evaluation of coatings.
