The sliding contact behavior is important for collecting current mechanism. In this study, the effect of ambient gas including inert gas on surface film formation and contact voltage drop was examined when the atmosphere is changed from low pressure to atmospheric pressure. Furthermore, the sliding surface conditions were observed by SEM, EDX and XPS analyses after the test operation. From these results, in case of the sliding contact in inert gaseous environment (Nitrogen and Argon), it is confirmed that the contact voltage drop tends to increase as if oxide film may be formed. However, it is made clear that any chemically generated surface film is hard to be formed in the inert gases environment by the chemical element analysis. As for these phenomena, we propose a model for physically absorbed surface film, and the relationship between inert gases and sliding contact phenomena is discussed.
