Abstract A sliding contact is normally used to supply current to a rotating or moving object. The surface film formed on the sliding surface is important for ensuring reliability and long life. In the present study, the effects of preoperation conditions and initial surface condition are investigated. We examined the relation between sliding speed and chemical treatment for electrical sliding contact action. The initial surface condition and preoperation conditions greatly influence the contact voltage drop that occurs during operation. It is shown that stability of sliding contact can be achieved by appropriate surface treatment and preoperation conditions. © 2010 Institute of Electrical Engineers of Japan.
