An analysis of equivalent electric currents corresponding to different operating conditions of friction pairs is made. The influence of thermoelectric effects on friction cutting of metals is examined. The value of the thermo EMF induced for stressed sliding regimes, and still more so, resistance of contact varies within very wide limits. A strong thermoelectric current passing along an interface acts as a stimulus to adhesion, seizure, and electrodiffusive, sintering of materials. High frequency vibrations of the contacting metal, interruptions in the thermo electric circuits transmitting current, produce a potentiality for natural electric microerosion of rubbing surfaces.
