Abstract
The degradation process in fretting fatigue is due to mechanical and chemical attack between two contacting surfaces, being directly related to wear, corrosion and fatigue. There are many parameters that influence the fretting fatigue phenomenon out of which relative displacement, δ , normal load, n F , and tangential load t F , are the most important and consequently the most studied ones. This paper describes the fretting fatigue phenomenon occurring on a high strength aluminium alloy, Al7175. The aim of this study is to achieve a better understanding of the fretting fatigue behaviour by observing the evolution of the fatigue life of the specimen with the normal load, the tangential load and the relative displacement amplitude.
