摘要
It is possible to enhance the high tempera- ture oxidationresistance and thus prolong the life time of non-oxide refractoriesby the application of oxide coating. In this work, silicon nitridebonded silicon carbide refracto- Ries were coated with alumina usingthe plasma spraying Technique. X-ray diffraction showed γ-Al_2O_3 tobe the Dominent phase in the as-sprayed alumina coatings.
