Abstract
Using optical and confocal laser microscopes it was shown that dry sliding of structural steel against hardened steel under electric current of density higher 250 A/cm2 was accompanied by the formation of composite tribolayers. By X-ray phase analysis of the surface layers of the sample and counterbody was shown that they contain α-Fe, γ-Fe, and FeO. It is noted that the self-organization of the tribosystem under conditions of dry sliding under electric current can be represented as a hierarchy of structural states of the surface layers of contacting materials. It was found that the nominal sample area had two sectors. The character of the contact interaction in the sectors differs from each other.
