The structurization of aluminum coatings on steel 20 and 40 substrates produced in different ESD modes is considered. The thickness and microhardness of ‘white’ and transition layers and the surface roughness increase and chemical and phase compositions change with higher discharge energy. The coating formed at low discharge energies mainly consists of α-Fe and aluminum oxides. Electron microprobe analysis shows that the coating produced at high discharge energies consists of iron and aluminum intermetallics and free aluminum. Compared to steel 20, the electrospark-deposited coating on steel 40 has a deeper layer with increased hardness and has greater microhardness. The surface roughness remains virtually the same. To decease roughness and increase integrity of the coatings, we recommend electrospark deposition with the same electrode (aluminum), but at lower discharge energies (Wd = 0.52 J).
