Binary and ternary lubricious oxides for high temperature tribological applications: A review

Abstract

Oxides and oxide-based coatings have been widely used as solid lubricants in demanding operating conditions to achieve low friction and wear due to their higher thermal and chemical stability. However, their tribological performance is highly dependent on the test temperatures and the surrounding environment. This article provides a comprehensive review of low-friction oxides and oxide-based coatings in relation to the influence of operating temperature on their tribological performance and their potential use as solid lubricants. Special emphasis is placed on the tribological behavior of binary and ternary oxides developed over the last few decades. Furthermore, this review summarizes the high temperature tribology, mechanisms and interfacial processes of the oxides leading to low friction coefficient and wear in high temperature applications.
