The present invention provides a coated component and methods of making and using the same. The coated component includes: a ceramic matrix composite substrate comprising silicon carbide and having a surface, ie, a CMC substrate; a mullite/NOSC bond coat on the substrate surface; and an environment on the mullite/NOSC bond coat Barrier coating. The mullite/NOSC bond coat includes a non-oxide silicon ceramic phase, or NOSC phase, contained within a mullite phase, and the mullite/NOSC bond coat comprises 60% to 95% mullite by volume phase, such as a mullite phase from 65% to 93% by volume. |
