  • Mitigating pyrophoric deposits during SiC CVI/CVD processes by introducing a mitigation agent into an exhaust conduit downstream of a reaction chamber
    Patent number: 11713281
    Abstract: Systems for and methods of manufacturing a ceramic matrix composite include introducing a gaseous precursor into an inlet portion of a reaction furnace having a chamber comprising the inlet portion and an outlet portion that is downstream of the inlet portion, and delivering a mitigation agent, such as water vapor or ammonia, into an exhaust conduit in fluid communication with and downstream of the outlet portion of the reaction chamber so as to control chemical reactions occurring with the exhaust chamber. Introducing the gaseous precursor densifies a porous preform, and introducing the mitigation agent shifts the reaction equilibrium to disfavor the formation of harmful and/or pyrophoric byproduct deposits within the exhaust conduit.
    Type: Grant
    Filed: December 21, 2021
    Date of Patent: August 1, 2023
    Assignee: GOODRICH CORPORATION

  • Mitigating pyrophoric deposits in exhaust piping during SIC CVI/CVD processes by introducing water vapor into an outlet portion of a reaction chamber
    Patent number: 11236021
    Abstract: Systems for and methods of manufacturing a ceramic matrix composite include introducing a gaseous precursor into an inlet portion of a reaction furnace having a chamber comprising the inlet portion and an outlet portion that is downstream of the inlet portion, and delivering a mitigation agent, such as water vapor or ammonia, into an exhaust conduit in fluid communication with and downstream of the outlet portion of the reaction chamber so as to control chemical reactions occurring with the exhaust chamber. Introducing the gaseous precursor densities a porous preform, and introducing the mitigation agent shifts the reaction equilibrium to disfavor the formation of harmful and/or pyrophoric byproduct deposits within the exhaust conduit.
