Chromium-coated silicon carbide fiber-reinforced ceramic matrix composites are potentially applicable to accident tolerant fuel cladding in light water reactors. Cr-coated silicon carbide composite, chemical vapor deposited silicon carbide, and pure Cr-metal were oxidized in 100% steam at atmospheric pressure for 4 hours using a thermogravimetric analyzer. Post-oxidation chemical analysis, phase identification and microstructural characterization indicates that the Cr coating layers did not adversely affect silicon carbide substrate under these conditions.
