Abstract
To effectively perform root cause analysis of hydraulic wear problems and system failures, it is vital that the fundamental wear processes be correctly recognized and understood. In this paper, fundamental potential pump wear problems will be illustrated pictorially and the mechanisms of these processes will be discussed. Some of the wear processes to be discussed include: abrasion, adhesion, cavitation, rolling contact fatigue, corrosion, and lubrication failure. It is expected that this discussion will provide a basic background to facilitate understanding of the more complex wear processes to be discussed during this conference.
