Abstract
Official abstract text for this publication.
A ceramic article includes a ceramic matrix composite that has a porous reinforcement structure and a ceramic matrix within pores of the porous reinforcement structure. The ceramic matrix composite includes a surface zone and a glaze material within pores of the surface zone and on an exterior side of the surface zone as an exterior glaze layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A ceramic article comprising: a ceramic matrix composite including a porous reinforcement structure and a ceramic matrix within pores of the porous reinforcement structure, the ceramic matrix composite including a surface zone; and a glaze material within pores of the surface zone and on an exterior side of the surface zone as an exterior glaze layer on the ceramic matrix composite, the glaze material containing elemental silicon and elemental metal selected from the group consisting of boron, titanium, vanadium, chromium, zirconium, niobium, molybdenum, ruthenium, rhodium, hafnium, tantalum, tungsten, rhenium, osmium, iridium and combinations thereof, and the ceramic matrix composite including an interior zone under the surface zone, the interior zone being free of any of the glaze material and having a greater porosity than the surface zone, wherein the glaze material excludes ceramic material. 2. The ceramic component as recited in claim 1 , wherein the elemental metal is selected from the group consisting of boron, zirconium, and combinations thereof. 3. The ceramic component as recited in claim 1 , wherein the elemental metal is selected from the group consisting of vanadium, molybdenum, hafnium, tantalum, and combinations thereof. 4. The ceramic article as recited in claim 1 , wherein the glaze material on the exterior side is a solid, continuous layer. 5. The ceramic component as recited in claim 1 , wherein free metal is selected from the group consisting of titanium, vanadium, chromium, zirconium, niobium, molybdenum, ruthenium, rhodium, hafnium, tantalum, tungsten, rhenium, osmium, iridium and combinations thereof. 6. The ceramic component as recited in claim 1 , wherein free metal is selected from the group consisting of titanium, chromium, hafnium, and combinations thereof. 7. The ceramic component as recited in claim 1 , wherein the porous reinforcement structure is a fibrous structure having at least one of ceramic fibers or carbon fibers. 8. A ceramic article comprising: a ceramic matrix composite including a fibrous reinforcement structure and a ceramic matrix within pores of the fibrous reinforcement structure, the ceramic matrix composite including a surface zone; and a glaze material within pores of the surface zone and on an exterior side of the surface zone as an exterior glaze layer on the ceramic matrix composite, the glaze material including elemental silicon and an elemental metal selected from the group consisting of boron, titanium, vanadium, chromium, zirconium, niobium, molybdenum, ruthenium, rhodium, hafnium, tantalum, tungsten, rhenium, osmium, iridium and combinations thereof, and the ceramic matrix composite including an interior zone under the surface zone, the interior zone being free of any of the glaze material and having a greater porosity than the surface zone, wherein the glaze material excludes ceramic material. 9. The ceramic component as recited in claim 8 , wherein the elemental metal is selected from the group consisting of boron, zirconium, and combinations thereof. 10. The ceramic component as recited in claim 8 , wherein the elemental metal is selected from the group consisting of vanadium, molybdenum, hafnium, tantalum, and combinations thereof.
