In the rapidly growing field of electrification of mechanical systems, such as electric vehicles (EVs), it is needed to understand how electric currents affect lubricated mechanical interfaces. In this research, we employed a ball-on-disc tribometer to analyze the friction and wear behavior under varying direct current (DC) conditions (0, 1, 2, 3 A) on the steel contact surfaces lubricated with lithium base grease. To study the influence of electrical parameters on the mechanical behaviors of the interface, the impedance of the contact was measured with an alternating current (AC). The results revealed 35 % increase in coefficient of friction and 670 % rise in wear under 3 A compared to non-electrified conditions. Furthermore, the effect of operational speeds on the pitting density and electrical impedance were analyzed. Lower impedance was measured in at low speed, which increases the likelihood of electrical discharges and subsequent wear. Consequently, as sliding speed increases from 0 to 5 cm/s, the pitting density on lubricated surfaces significantly decreases from 1.8 to 0.4 pits per square micrometer. This study laid a groundwork for future research aimed at reducing wear and extending the lifespan of lubricated mechanical systems under the influence of electrical currents.
