Abstract

This chapter reviews the fundamental nature of wear under lubricated conditions and presents a comprehensive view of our current understanding of the wear processes under boundary lubrication conditions. Wear under lubricated conditions can be classified into two main classes: well-lubricated systems and marginal lubricated systems. Past studies tend to focus on two phenomena: wear mechanism in the substrate beneath the surface and the chemical and physical mechanisms within the interfacial layer which includes the lubricant, lubricating film, and transfer films. In the wear literature, the focus is on understanding the wear mechanisms and how materials can be improved for wear resistance. Many of the wear studies are therefore either not lubricated or marginally lubricated. Wear data analyses also tend to focus on how wear progresses under dry wear conditions. In this chapter, we use dry wear as a baseline in assessing and comparing lubricated wear phenomena, wear measurement techniques, data interpretation, and the various assumptions behind normal wear interpretations. Lastly, the current modeling of lubricated wear is reviewed.
