abstract

• An article includes a silicon-containing region including surface features on a surface thereof. The surface features include depressions, protuberances, or combinations thereof. At least one outer layer overlies the surface of the silicon-containing region. A constituent layer is provided on the surface of the silicon-containing region and between and contacting the silicon-containing region and the at least one outer layer. The constituent layer is formed by constituents of the silicon-containing region and is susceptible to creep within an operating environment of the article. The surface features physically interlock the at least one outer layer with the silicon-containing region through the constituent layer.
