Articles for high temperature service and methods for their manufacture |
摘要 |
An article (200) for use in aggressive environments is presented. In one embodiment, the article (200) comprises a substrate (202) and a self-sealing and substantially hermetic sealing layer (210) disposed over a bondcoat (204). The substrate (202) may be any high-temperature material, including, for instance, silicon-bearing ceramics and ceramic matrix composites. A method for making such an article is also presented. The method comprises providing a substrate (202); disposing a self-sealing layer (210) over the substrate (202); and heating the sealing layer (210) to a sealing temperature at which at least a portion of the sealing layer (210) will flow. |
