Prediction of electrical contact resistance failure of Ag/Ag plated contact subjected to complex fretting-reciprocating sliding

Electronic connectors are extensively used in the car industry. However, due to engine vibration, fretting wear damage can decay the electrical contact resistance. In addition to small fretting oscillations, the connectors are subjected to clipping/unclipping, which also affects the Electrical Contact Resistance (ECR) endurance (i.e., Nc fretting cycles when ΔR>ΔRc=4 mΩ). To investigate this complex tribological process, an homogeneous Ag-Ni /...
