  • Measuring temperature of metallic part under uniaxial deformation pressure by optical pyrometry
    Patent number: 10107690
    Abstract: A method for preparing a metal part pressurized under isentropic, shock-type or compression-type, uniaxial deformation conditions, so as to measure the temperature of same by optical pyrometry. The method includes forming an emissive coating on a face of the metal part, having a thickness of 250 to 550 nm, and fixing an anvil-shaped window on the emissive coating. The emissive coating includes a first and a second layer of amorphous carbon, the first layer being inserted between the face of the metal part and the second layer, and having a carbon hybridization rate sp3 greater than the carbon hybridization rate sp3 of the second layer. A method for measuring, by optical pyrometry, the temperature of a metal part pressurized under isentropic, shock-type or compression-type, uniaxial deformation conditions.

  • METHOD FOR PREPARING A METALLIC PART IN SUCH A WAY AS TO IMPROVE THE MEASUREMENT OF THE TEMPERATURE OF SAME BY OPTICAL PYROMETRY DURING PRESSURISATION OF SAME UNDER UNIAXIAL DEFORMATION CONDITIONS
    Publication number: 20180120164
    Abstract: A method for preparing a metal part pressurised under isentropic, shock-type or compression-type, uniaxial deformation conditions, so as to measure the temperature of same by optical pyrometry. The method includes forming an emissive coating on a face of the metal part, having a thickness of 250 to 550 nm, and fixing an anvil-shaped window on the emissive coating. The emissive coating includes a first and a second layer of amorphous carbon, the first layer being inserted between the face of the metal part and the second layer, and having a carbon hybridisation rate sp3 greater than the carbon hybridisation rate sp3 of the second layer. A method for measuring, by optical pyrometry, the temperature of a metal part pressurised under isentropic, shock-type or compression-type, uniaxial deformation conditions.
