Deposition of material onto ceramic matrix composites

A process for remediating a ceramic containing material comprising the steps of:

• cleaning at least a portion of a location on a surface of at least one of the following:
• a coated preform, a partially densified ceramic matrix composite, and combinations thereof, to form a cleaned location;
• masking the surface, except for the cleaned location, with a maskant to form an aperture exposing the cleaned location;
• shaping the aperture to form a shaped, exposed cleaned location;
• loading any one or more of the coated preform, the partially densified ceramic matrix composite, and combinations thereof, into a reactor chamber of a chemical vapor infiltration apparatus;
• depositing a material onto the shaped exposed location to form a location having a deposited material;
• densifying the deposited material to form a ceramic matrix composite comprising a surface having a densified location;
• and
• reshaping the densified location to form a reshaped densified location.

A process for repairing a ceramic matrix composite component comprising the steps of:

• cleaning at least a portion of a location on a surface or a bulk area of the ceramic matrix composite component to form a cleaned location;
• masking the surface, except for the cleaned location, of the ceramic matrix composite component with a maskant to form an aperture exposing the cleaned location;
• shaping the aperture to form a shaped, exposed cleaned location;
• loading the ceramic matrix composite component into a reactor chamber of a chemical vapor infiltration apparatus;
• depositing a material onto the shaped exposed location to form a location having a deposited material;
• densifying the deposited material to form a densified location on the ceramic matrix composite component;
• and
• reshaping the densified location to form a reshaped densified location on the ceramic matrix composite.
