| titleOfInvention | Alumina/aluminate sealant for silicon containing substrate |
| abstract | An article 12 comprising a silicon-containing substrate 30, an environmental barrier coating (EBC) 42 overlying the substrate. The EBC comprises a higher metal silicate-containing outer barrier layer 66, and a subsequent corrosion resistant alumina/aluminate sealant 74. Higher metal silicates include silicates of Sc, Y, Zr and Hf. A process is also provided for forming a corrosion resistant alumina/aluminate sealant layer over the higher metal silicate-containing outer barrier layer. Also provided is an alternative process for treating a porous higher metal silicate-containing outer barrier layer with a liquid composition comprising an corrosion resistant alumina/aluminate sealant precursor to infiltrate the porous higher metal silicate-containing outer barrier layer with the alumina/aluminate sealant precursor in an amount sufficient to provide, when converted to the corrosion resistant alumina/aluminate sealant, protection of the environmental barrier coating against environmental attack; and converting the infiltrated alumina/aluminate sealant precursor within the porous higher metal silicate-containing outer barrier layer to the corrosion resistant alumina/aluminate sealant. The sealant may comprise calcium aluminate alpha alumina etc. |
