It is important to understand tribological characteristics of components operating in a hydrogen atmosphere. For instance, piston rings used in reciprocating compressors require strength, heat resistance and wear resistance, hence resins containing f

Abstract The boundary lubrication mechanism at the articulating surface of natural synovial joints has been the subject of much discussion in tribology. In this study, to elucidate the lubricating function of the superficial area of articular cartila

A new tribo experiment system is developed for sliding tests under high purity gas environments including hydrogen. It uses a transfer vessel such that surface oxidation does not substantially occur during transfer of specimens to surface analyzers.
