Abstract
A method for manufacturing a contact temperature sensor to be used at a temperature of use, including a) supplying a carbon fiber; b) heat treating of the fiber at a temperature higher than 800° C. and higher than the temperature of use; c) full layer depositing on the fiber, at a deposition temperature, an electrically insulating ceramic coating layer stable at the temperature of use, the ceramic material chosen among silica (SiO), zirconia (ZrO), and alumina (AlO); d) heat treating of the fiber, coated with the coating layer, at a temperature higher than the deposition temperature of the coating layer and higher than the temperature of use, or (c') full layer depositing on the fiber a first coating layer of silicon carbide; d′) full layer depositing the first coating layer a second coating layer of boron nitride; e′) heat treating the fiber thereby obtained at a temperature above the deposition temperatures and the temperature of use of the sensor.
