Abstract : The scientific literature often contains data to the effect that lubricating oils of various types operate under conditions of an electric field. The appearance of an electric field is attributed to various causes, one of which is electrochemical emf. However, when rubbing parts separated BY AN OIL FILM SLIDE AT HIGH VELOCITIES, HIGH ELECTRIC POTENTIALS, CAUSED BY ELECTROSTATIC CHARGING OF THE LUBRICANT DURING FRICTION AND DEFORMATION, CAN DEVELOP IN ADDITION TO ELECTROCHEMICAL POTENTIALS. The electrostatic charging of heavy lubricants during their deformation in a rotation plastoviscometer was caused by the development of electrokinetic potentials due to the mutual displacement of the disperse phase (coagulant) and dispersion medium (oil). Electric charging of mineral oils and other hydrogen liquids during their friction on a metal surface takes place, as is shown in the report, despite the absence of a disperse phase. (Author)
