    摘要: The disclosure provides for an article (10) including a substrate (12), an environmental barrier coating (EBC) (16), a bondcoat (14), and a boron source (20). The substrate (12) includes a silicon-including material. The EBC (16) is disposed over the substrate (12), and the bondcoat (14) is disposed between the substrate (12) and the EBC (16). The bondcoat (14) includes silicon. The boron source (20) is disposed within the article (10) to provide an effective amount of boron to form an oxide (18) including silicon and at least 0.1 weight percent boron during exposure of the bondcoat (14) to an oxidizing environment at a temperature greater than 900 degrees Celsius. The oxide (18) may be a borosilicate glass that is substantially devitrification resistant to prevent spallation of the EBC (16) and thereby enhance the temperature capability of the article (10).

    摘要: A silicon carbide-based porous body comprising a plurality of silicon carbide (SiC) particles as an aggregate and a binder which binds the silicon carbide particles to each other, wherein
    the content of the binder, i.e. [100×binder/(silicon carbide particles + binder)] is 5 to 70% by volume,
    the open pore ratio is 30 to 70%, and
    the binder contains at least one member selected from the group consisting of a Ti silicide, a Zr silicide, a Mo silicide and a W silicide, in an amount of at least 60% by volume of the total binder. The silicon carbide-based porous body can avoid excessive temperature elevation when it is used as a filter and the particulate matter (PM) captured thereby is burnt and removed.
