Abstract: A method and a device for generating a plasma in atmospheric-pressure, low-temperature conditions are described herein. The device described for the generation of the plasma comprises a first pair of electrodes, each of which separated by a dielectric layer and externally positioned with respect to a tubular duct where the gas flows, and a second pair of electrodes, also in this case each of which separated by a dielectric layer and externally positioned with respect to said tubular duct where the same gas flows downstream with respect to the first pair with respect to the direction of the flow. A high-frequency excitation is applied to the first pair of electrodes while a Radio-Frequency excitation is applied to the second pair of electrodes. The plasma generated in this manner emerges from the gas flow at the outlet of the transport duct.

Abstract: The invention refers to a method for the repair of an aluminium alloy component, in particular a precipitation-hardened aluminium alloy component, comprising the steps of: a) depositing by cold spray on said component to be repaired a portion of supplied material, thus obtaining a partially repaired component; b) subjecting said partially repaired component to a thermal treatment, thus obtaining a repaired component, the conditions of performance of said thermal treatment being selected according to the composition and dimensional tolerances of said component.

Abstract: The invention relates to a method for manufacturing a massive component substantially wholly made of intermetallic material, comprising the steps of: a) preparing a mixture of powders of at, least two metallic elements, the powders being present in the mixture in a proportion by weight corresponding to the atomic percentage in which the at least two metallic elements are present in a corresponding intermetallic compound which may be formed from these metallic elements; b) applying a plurality of layers of such a mixture of powders by cold spraying on a substrate so as to obtain, on the substrate, a preform of metallic mixture of predetermined thickness; c) thermally treating at least the preform of metallic mixture so as to cause the reaction between the at least two metallic elements to form the corresponding intermetallic compound; and d) removing the substrate, thus obtaining the massive component made of intermetallic material.
