  • Method of making a deposit on an SiC-covered substrate
    Patent number: 7950139
    Abstract: The invention relates to a method of depositing a coating on a part having its surface made of silicon carbide. The method comprises the following steps: a) applying laser treatment to the SiC surface by superposing laser impacts for the purpose of increasing the roughness of said surface; and b) depositing a coating on the SiC surface by atmospheric thermal spraying. The invention also provides a device for measuring deformation, which device comprises a first alumina coating obtained by atmospheric thermal spraying onto the silicon carbide layer covering the substrate of the part after it has been treated by superposing laser impacts, a free filament strain gauge placed on the coating, and an additional alumina coating obtained by atmospheric thermal spraying onto the strain gauge.
