The results of the study of the shape, morphology and elemental composition of aluminum powder particles obtained in distilled water with the following electrical parameters of the electroerosive dispersion unit are presented: the capacity of discharge capacitors is 65 μF, voltage 100 V, pulse frequency 50 Hz. It is established that the powder consists of particles of regular spherical shape (or elliptical), irregular shape (conglomerates) and fragmentation, and the main elements of the powder are aluminum and oxygen. The obtained powder materials can be used for the manufacture of powder electrodes used in welding and surfacing of a wide range of parts.

The paper presents the results of a study and comparison of the corrosion resistance of gas-dynamic coatings, obtained using standard powder material grade A-20-11, and aluminum-containing powder material, obtained by the method of electroerosive dispersion of electrical aluminum wastes in distilled water. The study of the corrosion resistance of gas-dynamic coatings was carried out according to the method of accelerated testing using a multichannel potentiostat-galvanostat "Elins P-20X8". 3,5% NaCl was used as working solution. The ESr-10101 electrode (Ag/AgCl/KCl) was used as a reference electrode, the KCl concentration in the potential-forming half-cell was 4,2mol/dm3. The reference electrode was connected to the working solution via an electrolytic switch (bridge). The area of the investigated surface was 1 cm2. The volume of working solution used for each sample was 1 l. The measurement time was 5 hours. As a result of the corrosion resistance study of gas-dynamic coatings, it was experimentally established that in coatings, obtained using standard powder materials, the electrolyte penetrates into the coating, which contributes to the rapid exfoliation. It was also established that the corrosion resistance of the coating obtained using electroerosive powder materials is 22% higher than the corrosion resistance of the coating obtained using standard powder materials.
