Fig. 1From: Nanoparticles formation mechanisms through the spark erosion of alloys in cryogenic liquidsPrincipal scheme of the spark erosion working chamber. A similar chamber was used for the powder elaboration [26]. Round inset shows the formation during the spark discharge between the granules (1) the molten droplets, (2) the evaporated constituents of material, and (3) the irregular broken fragments of material piecesBack to article page
