ABSTRACT:
The coated article includes a refractory metal substrate having an oxidation resistant intermetallic layer formed in situ thereon; e.g., a fused refractory metal silicide layer, and a ceramic layer applied on and adhering to the intermetallic layer to provide enhanced high temperature properties and improved resistance to premature catastrophic failure in high temperature oxidizing environments where dissimilar materials are present that may destructively react with the intermetallic layer.
