Zusammenfassung:A composite article includes a substrate (22) and a multilayer coating (24) on the substrate (22). The multilayer coating (24) includes an inner layer (26) near the substrate (22), and outermost layer (28) on the inner layer (26), and an intermediate layer (30) between the inner layer (26) and the outermost layer (28). The inner layer (26) and outermost layer (28) are boron-containing materials, and the intermediate layer (30) is a silicon-containing ceramic material.
