Abstract
A method for producing nanostructured coatings on a substrate, comprising: preparing a nanocrystalline powder of a powder size comprised between 1 and 60 μm; and combining cleaning the surface of the substrate and cold spraying the nanocrystalline powder on the surface of the substrate, and a system for producing nanocrystalline coatings on a substrate, comprising a spray head, a cleaning head and a handling system monitoring the spray head and the cleaning head relative to the substrate to be coated, the spray head being a first cold spray head, the first cold spray head depositing on the substrate at least one nanocrystalline powder, the cleaning head optimizing the surface being coated with the at least one layer of nanocrystalline powder.
