N2 - Employing a new analytical model, this paper studies the role of geometry and material combination in the tribocorrosion current of metal-on-metal contacts. Experiments were conducted on ZrO2-on-(Ti/CoCr) and (Ti/CoCr)-on-(Ti/CoCr) at 1–20 Hz in PBS. The contribution of the ball and disk in the tribocorrosion current was determined. The results showed that the disk was dominant in (CoCr/Ti)-on-CoCr at 1–10 Hz; whereas, at 20 Hz, the ball dominated the current. For Ti-on-Ti, the ball controlled the current at 1–20 Hz. In CoCr-on-Ti, the disk played the main role at 5–20 Hz while the ball dominated the interface at 1 Hz.
