Abstract
In some examples, a slurry infiltration fixture. The infiltration fixture includes a fixture main body that includes a slurry introduction channel and a plurality of fixture walls defining a cavity configured to receive a porous component. The cavity includes a component volume and a reservoir volume. The plurality of fixture walls includes a shape configured to define a fixed offset between the porous component and the plurality of fixture walls and a fixed volume for slurry between the plurality of fixture walls and the porous component. The slurry introduction channel is configured introduce the slurry into the cavity through an opening proximate a bottom of the cavity.
Claims19
A slurry infiltration fixture comprising:
- a fixture main body that comprises a slurry introduction channel and a plurality of fixture walls defining a cavity configured to receive a porous component, wherein the cavity includes a component volume and a reservoir volume;
- wherein the plurality of fixture walls form a shape which defines a fixed offset between the porous component and the plurality of fixture walls and a fixed volume for slurry between the plurality of fixture walls and the porous component;
- and
- wherein the slurry introduction channel is configured to introduce the slurry into the cavity through an opening proximate a bottom of the cavity, wherein the slurry introduction channel extends through the fixture main body from an inlet proximate the top of the fixture main body to the opening proximate the bottom of the cavity.
A method of slurry infiltration, the method comprising:
- positioning a porous component in a component volume of a cavity defined by a fixture main body of a slurry infiltration fixture, wherein the cavity includes the component volume and a reservoir volume, wherein the fixture main body defines a slurry introduction channel, wherein the plurality of fixture walls form a shape which defines a fixed offset between the porous component and the plurality of fixture walls and a fixed volume for slurry between the plurality of fixture walls and the porous component;
- and
- introducing slurry into the cavity through the slurry introduction channel, wherein the slurry introduction channel comprises an opening into the cavity proximate to a bottom of the cavity, and wherein the slurry introduction channel extends through the fixture main body from an inlet proximate the top of the fixture main body to the opening proximate the bottom of the cavity.
