Abstract

By utilization of preceramic polymer of polymethylsiloxane (PMS), a $MoSi_2$SiOC/SiC ceramic composite was fabricated. The prepared composite displayed superior high temperature oxidation resistance by forming $SiO_2$ on the surface. The thin $SiO_2$ layer had some surface cracks, but they had not adversely deteriorated the oxidation resistance. The composite fabrication method employed in this study can be applied to protect any possible substrate material from aggressive oxidative attack, if the composite were coated on the substrate material.
