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.

A coated article comprising a substrate of a refractory metal, an oxidation resistant intermetallic silicide layer fused in situ to the substrate and including by a reaction therewith an oxidation resistant silicide compound of the refractory metal, and a ceramic layer adhered to the intermetallic silicide layer and stable in high temperature oxidizing environments and at the interface with the silicide layer, said intermetallic silicide layer having a surface roughness of at least about 160 micro-inches RMS to promote adherence of the ceramic layer thereon.
