Abstract
Current dependences of the electrical conductivity and wear rate of a steel—steel 45 electrical contact under dry friction at a current density of over 100 A/cm2 are presented. It is found that an increase in the concentration of the alloying elements or the hardening phases in the original steel structure leads to a low strength of the surface layer, which manifests itself as a high wear rate of the contact and catastrophic wear at a low current density.
