Abstract
A composite article includes a substrate, at least one protective layer on the substrate and an intermediate layer between the at least one protective layer and the substrate. The intermediate layer includes dense silicon oxycarbide.
Claims27
A composite article comprising:
- a substrate;
- at least one protective layer on the substrate;
- and
- an intermediate layer between the at least one protective layer and the substrate, the intermediate layer including dense silicon oxycarbide, the dense silicon oxycarbide being an amorphous compound and having an average composition of SiOxCy, where x<2 and y>0.

A composite article comprising:
- a substrate including a silicon-containing material;
- at least one protective layer on the substrate, the at least one protective layer being free of any layers that contain at least one of metallic silicon or a metallic alloy;
- and
- an intermediate layer between the at least one protective layer and the substrate, the intermediate layer including regions of silicon oxycarbide that are dispersed within a matrix, and the regions of silicon oxycarbide are in direct contact with intermediate regions interposed between the regions of silicon oxycarbide and the matrix.
