Abstract: A device for conducting accelerated aging tests of a coating, notably an outer coating for an aircraft, in particular allowing the testing of the durability of the coating after having been subject to all kinds of stresses, is desired. An object of the disclosure thus relates to such a device including test chambers subject to different and/or independently controllable test parameters, and including light for generating photo-oxidation, the device including a support for a sample of the coating, displaceable between the chambers for generating mechanical stresses by thermal shocks. The disclosure herein finds applications in many fields of industry, and preferentially in the field of aeronautics.

Abstract: A method for treatment of two surfaces, each surface belonging to a metal part which is designed to be painted, the two surfaces being secured adjacent to one another or one on top of the other. The treatment method comprising a sandblasting step during which each surface is subjected to sandblasting, a projection step during which each surface thus sandblasted is subjected to thermal projection of an aluminum alloy, such as to compensate for the divergences between the two surfaces, and a finishing step during which the layer of aluminum alloy thus projected is subjected to mechanical finishing, such as to constitute a coating with a homogeneous surface.
