“…The most efficient method to reduce fretting wear damage consists in applying noble coatings. Gold layers are currently the most used coatings due to their high electrical conductivity and high corrosion resistance [12][13][14]. However, due to the expensive price of gold, silver is now considered as a promising alternative [15][16][17].…”

“…Since the first studies realized by Antler [1], [2], the decay of electrical contact induced by fretting has been extensively investigated [3][4][5][6][7][8][9][10][11][12]. The best solution to reduce damage is to apply noble coatings such as gold and silver layers.…”

During the last decades, the use of connectors in electrical devices for automotive has significantly increased. This raise in the number of electrical and electronic devices on board has led to a growing number of breakdowns. Indeed, this connectors need to keep a low and stable electrical contact resistance (ECR) but due to engine vibrations, fretting wear damage occur. Characterized by small oscillatory motions, fretting induces wear and oxide debris layer (third body) decaying the electrical contact resistance. The aim of this work is to study the effects of two main factors which are the normal contact force and the displacement amplitude. In this study, a silver-plated contact (2µm of thickness) was investigated applying various loading parameters: 2 N < P < 6 N and ± 3µm < δ* < ± 20 µm. Results show that the ECR endurance decreases when the displacement amplitude increases regardless of the normal force. However, a non-monotonic evolution is found regarding normal force effect. Indeed, for a given displacement amplitude, a rise of the normal force tends to increase the contact pressure but at the same time induces a reduction of the effective sliding amplitude due a larger tangential accommodation. Hence by coupling a friction energy density approach with a basic compliance description, the synergic effect of the normal force and the displacement amplitude is described and the ECR endurance predicted.
