Summary

A reaction bonding method has been employed to produce an oxidation resistant layer on Si3N4 ceramics in order to enhance their oxidation resistance. Rare-earth silicate was selected as the oxidation resistant layer material and the oxidation behavior of the layered composites was evaluated and compared with non-coated Si3N4. It was found that the oxidation behavior of the rare-earth silicate on Si3N4 was better than non-coated Si3N4, because no cracking occurred between the oxide layer and the base material.
