Abstract

The structure and properties of the electroerosive powder fabricated from the electrotechnical aluminum waste are investigated, and the efficiency of application of electrodispersion is shown. It ensures the production of new powder materials suitable for additive technologies at low energy consumption. The fabricated powders are shown to have a spherical or elliptical shape; the main elements in them are Al and O; the main phases are Al2O3, Al2O3⋅3H2O, and Al(OH)3; and the aspect ratio of particles 25.489 μm in size is 1.245. 50% of the particles have a size of less than 25.489 μm. Note that 35% of the total sample volume is occupied by particles 20.0–50.0 μm in size.
