A method for forming a cathodic protection coating on a substrate forming a turbomachine part, includes deposition, on the substrate, of particles for cathodic protection of the substrate, this deposition being performed by electrophoresis from an organic electrolyte including the particles, and forming an inorganic matrix in pores of the deposit of particles produced in this way, including impregnating the deposit with an impregnation composition, drying heat treatment of the deposit impregnated by the impregnation composition, and densifying the deposit by mechanical compacting, after the drying heat treatment, in order to make the deposit electrically conductive.

A device is suitable for revealing spatial variations in polarization of an electromagnetic radiation, in a form of localized temperature variations. The device includes a surface of a carrier which is electrically and thermally insulating, and includes an array of patterns which each consist of at least one rectilinear segment of a sensitive material, of which the orientation is variable within each pattern or between neighboring patterns. Such device may be used with a thermal camera to reveal, in infrared images, temperature variations which are localized at segments not perpendicular to a local direction of linear polarization of the radiation.

A method for estimating the ageing of a battery powering an electrical system. A set of data about the voltage and current across the battery terminals, in response to the current perturbations provoked during the normal operation of the battery by the changes of consumption rate of the electrical system are stored. The impedance of the battery, within a predetermined frequency interval, from the voltage and current data is determined. The age of the battery as a function of the impedance is estimated by comparing the impedance with a previously stored model of evolution of this impedance with ageing.
