The current dependence of the electrical conductivity and wear intensity of a sliding electrical contact in air, glycerin, or electrolyte under electrolysis conditions at a contact current density of 100 A/сm2 is presented. The structural characteristics of the steel surface layer are shown to change due to the formation of the γ-iron and ferric carbide phases. Low phase content is found to cause...
Dependences of the electric conductivity of a contact and wear intensity of metal materials on the electric current density in sliding friction are obtained. It is established that alloying of the material basis leads to faster damage of the friction surface. The presence of about 40 аt.% oxygen in the surface layer is detected by the Auger spectrometry method. It is demonstrated by the x-ray diffraction...
