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: 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.
