  • Method for thermal treatment of a ceramic part by microwaves
    Patent number: 11713280
    Abstract: A field of thermal treatment of ceramic materials is provided, and relates to a method for thermal treatment of a solid ceramic part in a microwave cavity, the direction of the electrical field E being substantially uniform in an empty cavity, comprising the steps that consist of placing, in the cavity, at least one ceramic part surrounded by at least one first susceptor with dimensions, material and arrangement configured to emit infrared radiation, each first susceptor including at least one first main surface, each first main surface being an adjusted surface in which the cone distances are parallel to the electrical field E, and of emitting the microwaves into the cavity.
    Type: Grant
    Filed: October 20, 2017
    Date of Patent: August 1, 2023
    Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, UNIVERSITE DE CAEN NORMANDIE, ECOLE NATIONALE SUPERIEURE D'INGENIEURS CAEN, UNIVERSITE POLYTECHNIQUE HAUTS-DE-FRANCE, ASSOCIATION POUR LA RECHERCHE ET LE DEVELOPPEMENT DE METHODES ET PROCESSUS INDUSTRIELS-ARMINES
    Inventors: Sylvain Marinel, Etienne Savary, François-Xavier Lefevre, Jérôme Lecourt, Sébastien Saunier, Pauline Chanin-Lambert
  • Method for thermal treatment of a surface coating on a metal part by microwaves
    Patent number: 10882071
    Abstract: A process for treating a surface coating of a bulk metal part, comprises the steps of placing, in a cavity, at least one what is called metal part including what is called a surface coating that is able to absorb microwaves at the frequency ?0, the cavity being surrounded by one or a plurality of first susceptors the dimensions, material and arrangement of which are configured to screen the microwaves at the frequency ?0, in the vicinity of each the metal part, and in emitting the microwaves at the frequency ?0 into the cavity.
