Transfer Lubrication for High Temperatures: A Review

Abstract

Transfer lubrication is defined as lubrication provided by the continuous transfer of solid lubricant to sliding/rolling interfaces. The lubricant may either be incorporated within a self-lubricating composite or supplied from an auxiliary component. Both routes require similar research information on the factors influencing film formation, friction and wear, and film failure. This paper reviews what is known about these aspects for solid lubricants appropriate to high temperature applications (≥300°C). Areas are identified in which further research is needed.
