Quasi‐Static and Dynamic Sliding Characteristics of Teflon—Stainless Steel Interfaces
Publication: Journal of Structural Engineering
Volume 116, Issue 10
Abstract
This paper describes an experimental program of study on the sliding characteristics of Teflon‐stainless steel interfaces. The effects of normal pressure, sliding distance, normal pressure history, sliding velocity, sliding velocity history, normal pressure rate, and sliding work are identified and interpreted. Test results show that the friction force is independent of the normal pressure history and the sliding velocity history, and is also irrelevant to the normal pressure rate. In addition, the dependence of dynamic friction force on the normal contact pressure and the sliding velocity can be uncoupled. The dynamic friction force can be determined by multiplying the quasi‐static friction force by an amplification factor. The reciprocal of the quasi‐static friction coefficient is linearly dependent on the normal pressure only, and the amplification factor is solely a function of velocity. Moreover, the dynamic friction force decays during sliding, and the decaying is a function of excess dynamic sliding work.
