Abstract
A porous metallic mat is provided. The porous metallic mat includes a plurality of fibers and a protective coating. The plurality of fibers is sintered into a mat configuration. The protective coating is provided on the porous metallic mat. The protective coating includes a diffusion aluminide configured to provide oxidation resistance to the porous metallic mat.
Claims9
A porous metallic mat comprising:
- a plurality of fibers sintered into a mat configuration forming a surface burner for a combustion chamber of a gas turbine engine, the surface burner having an outer burner surface and an inner surface and a plurality of pores configured to allow flow of a combustion mixture through the surface burner from the inner surface to the outer burner surface;
- and
- a protective coating provided on the fibers of the porous metallic mat, the protective coating extending over the inner surface and outer burner surface of the porous metallic mat and including a diffusion aluminide configured to provide oxidation resistance to the porous metallic mat.
A burner assembly comprising:
- a mounting ring;
- and
- a surface burner for a combustion chamber of a gas turbine engine, the surface burner having an outer burner surface and an inner surface and selective perforations, the surface burner configured to receive a combustion gas and air mixture and the selective perforations configured to allow flow of the combustion gas and air mixture from the inner surface to the outer burner surface, wherein the surface burner is constructed from a porous metallic mat, the porous metallic mat including:
- a plurality of fibers sintered into a mat configuration;
- and
- a protective coating provided on fibers forming the porous metallic mat, the protective coating extending over the inner surface and outer burner surface of the porous metallic mat and including a diffusion aluminide configured to provide an oxidation resistance for the porous metallic mat.
