Abstract

Abstract The wear is a very common physical phenomenon in the mechanical area. It can be observed in different mechanisms in different forms. Depending of the role of the mechanism in the assembly or subassembly of which it is part of, wear can happen. Thus, after a short analysis in the automotive area, it can be observed that in the fuel high pressure pumps, several forms of wear are encountered. Various levels of the wear can be studied. Depending of the working period and the operating conditions of the pump, various types of wear can occur, such as adhesion, corrosion, abrasion, fatigue or erosion. The purpose of this paper is to experimental study a type of wear often encountered in high pressure pumps, whose early identification can be useful in damages prevention in order to assure the pump performance. Some wear examples due to material fractures are described.
