A sputtered {gamma} (TiAl)+Laves TiAlCr coating formed an adherent Al{sub 2}O{sub 3} scale on SN 282 Si{sub 3}N{sub 4} when oxidized. A Ti-N rich layer was formed at the TiAlCr-Si{sub 3}N{sub 4} interface, which effectively resulted in beneficial local Al enrichment underneath the growing Al{sub 2}O{sub 3} scale, rather than detrimental Al loss to the substrate.
