A device () for coating a substrate () with nanometric sized particles, wherein the device comprises: a plurality of aerodynamic lenses able to product a jet () of nanometric sized particles, each of the aerodynamic lenses having a longitudinal axis, the aerodynamic lenses being arranged so that the various longitudinal axes are parallel and oriented in a first direction (X) defining the direction of propagation of the jet and in the form of at least two columns () offset from each other in a second direction (Y) orthogonal to the first direction, where the first and the second column each comprise at least one of the aerodynamic lenses, the at least one of the aerodynamic lenses of the first column also being offset relative to the at least one of the aerodynamic lenses of the second column in a third direction (Z) that is both orthogonal to the first direction and to the second direction.

Device for depositing nanometric sized particles onto a substrate

The invention relates to a nuclear fuel cladding comprising: i) a substrate containing a zirconium-based inner layer, optionally coated with at least one intermediate layer formed by at least one intermediate material selected from among tantalum, molybdenum, tungsten, niobium, vanadium, hafnium or the alloys thereof; and ii) at least one protective outer layer placed on the substrate and formed by a protective material selected from either chromium or an alloy of chromium. The nuclear fuel cladding produced using the method of the invention has improved resistance to oxidation/hydriding. The invention also relates to the method for the production of the nuclear fuel cladding by ion etching of the surface of the substrate and deposition of the outer layer on the substrate with a high power impulse magnetron sputtering method (HiPIMS), as well as to the use thereof to protect against oxidation and/or hydriding.

A structure () for aircrafts, includes a part () including a metal leading edge (), the leading edge () being covered by a coating () having a thickness which is less than or equal to ten micrometers and having a hardness higher than six hundred in the Vickers hardness test (HV). According to a mode of embodiment, the coating () is a multilayer stainless steel coating consisting of a superposition of layers with a low nitrogen gradient and layers with a high nitrogen gradient, the layers having a thickness essentially equal to a micrometer. An aircraft including such a structure is also described.
