  • Cermet materials and method for making such materials
    Patent number: 10920302
    Abstract: The invention relates to a cermet material comprising a first phase MAX having the general formula Tin+1AlCn and a second intermetallic phase having the general formula TixAly, where n equals 1 or 2, x is between 1 and 3, y is between 1 and 3, and x+y?4. The proportion by volume of the first phase in the material is between 70% and 95%. The proportion by volume of the second phase in the material is between 30% and 5%. The void ratio is less than 5%.
    Type: Grant
    Filed: February 5, 2016
    Date of Patent: February 16, 2021
    Assignee: OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES (ONERA)
    Inventors: Aurelie Julian-Jankowiak, Gilles Hug

  • Process for producing a ceramic matrix composite part
    Patent number: 9302946
    Abstract: The invention relates to a process for producing a ceramic matrix composite (CMC) part by infiltration of a suspension (S) of a ceramic powder into a fibrous reinforcement (14). A suspension (S) of ceramic powder containing particles of chosen particle size, dispersed in at least one solvent, is prepared. The infiltration of the suspension is carried out in a single step in the fibrous reinforcement (14) positioned between a mold (12) and a permeable membrane (16), which makes it possible to apply a vacuum (V) and to subsequently remove the solvent from the suspension through the permeable membrane (16). The invention applies to the production of large-sized parts of complex shape, in particular in the field of aeronautics and aerospace engineering.
