    摘要： A method for making a ceramic matrix composite component includes densifying a fibrous preform of the component with a ceramic matrix to form an intermediate component (10); infiltrating a hole (14) in the intermediate component (10) with an infiltrate material (22) comprising a solid and a metallic alloy whose reaction forms a carbide, silicide, boride or combination thereof, heating the infiltrate material (22) to a temperature in excess of a melting point of the metallic alloy; and sequentially cooling regions of the hole (14) starting from an interior end of the hole (14) to the outer surface (11) of the intermediate component (10) to form a solidified through-thickness reinforcement element (26). The hole (14) extends in a through-thickness direction and is open to an exterior surface of the intermediate component (10).

    摘要： A process for the manufacture of a zirconium oxide prosthesis, the zirconium oxide being stabilized, which process includes the following steps: a) compacting a zirconium oxide powder at a pressure of at least 45 MPa to an object of a desired form, b) impacting an etchable medium into the surface, c) optionally working the object to a final shape, d) sintering the body at a temperature of above 1170° C. to transfer zirconium oxide into a tetragonal crystalline structure, and e) etching the etchable medium using hydrofluoric acid to remove the medium and impart a micromechanical retention surface. A prosthesis prepared by this process is also disclosed.
