초록

[ ] was coated with , MgO and respectively by sol-gel method and cured at 900 and . The coated oxides did not react with at but reacted with it to form at . The specimen coated with at formed a dense protecting layer and showed the best oxidation resistance at in air. However, the dense protecting layers did not form in and MgO coated specimens cured even at . MgO coated specimen showed the worst improvement in the oxidation resistance because the reactivity of MgO with was highest. On the other hand, the electrical conductivities were measured in MgO and coated specimens to have TiCx but could not be measured in the coated ones because of the nonconductive dense protected layers.
