Fretting wear and fatigue represent a considerable and longstanding problem in applications using frictional contacts subjected to vibrations as e.g. fretting of tubes in steam generators and heat

I. INTRODUCTION Fretting wear process occurs when surfaces are degraded and materials are removed due to a small relative oscillatory motion between two contact surfaces. Due to the continuous change in the shape of a structure during its lifetime, the design of engineering components subjected to fretting wear is a challenge to engineers and scientists. Fretting wear is known as a complex contact phenomenon. A variety of factors, including surface roughness, have an influence on the fretting wear process. Thus, difficulty in simulating fretting wear persists. Some attempts are made to simulate fretting wear and to predict the lifetime of fretting wear.

Besides being a form of wear, fretting can have a deleterious effect on the fatigue life of parts which are subjected to it. fretting wear rate of the contact. This investigation also underlines how the application of sequential large reciprocatings can increase the fretting ECR endurance through a refilling process of fretting scar with silver transferred from the outer part of the lateral reciprocating track.
