There are considered the phase state and chemical composition of the aluminized coatings obtained by the method of electrospark alloying (ESA) on the specimens made of 20 steel. At low discharge energies, there is formed a layer predominantly consisting of α-Fe and aluminum oxides. It has been stated that increasing discharge energy results in obtaining the layer consisting of iron and aluminum intermetallics and free aluminum as well. A kinetic analysis of the system describing this process has been carried out, phase portraits have been constructed, which confirm the developed theory of a three-layer system.
