Une méthode de tomographie par capacité électrique (ECT) a été utilisée pour détecter le comportement d'usure par frottement des connecteurs électriques. Les échantillons utilisés dans cette étude étaient des contacts de connecteurs électriques ronds à deux broches de type M. Les expériences consistaient à effectuer une série de tests de vibration à chaque fréquence combinées à des niveaux de g. Au cours de chaque test, la capacité mesurée par paire d'électrodes a été surveillée en tant que caractéristique de performance, induite par les débris d'usure générés par l'usure par contact des connecteurs électriques. La surface frettée est examinée à l'aide d'une microscopie électronique à balayage (MEB) et d'une analyse par spectromètre à dispersion d'énergie (EDS) pour évaluer le profil de surface, l'étendue des dommages causés par le frettage et la distribution des éléments dans la zone de contact, puis comparée aux valeurs de capacité. Les résultats montrent qu'avec l'augmentation des cycles de frottement ou de la fréquence de vibration, la valeur caractéristique des débris d'usure entre les contacts du connecteur électrique augmente progressivement et l'usure est plus grave. Les valeurs de capacité mesurées sont cohérentes avec les analyses SEM et EDS.

Abstract: An electrical capacitance tomography (ECT) method was used to detect fretting wear behavior of electrical connectors. The specimens used in this study were contacts of type-M round two-pin electrical connectors. The experiments consisted of running a series of vibration tests at each frequency combined with one g levels. During each test run, the measured capacitance per pair of electrodes was monitored as a performance characteristic, which is induced by the wear debris generated by the fretting wear of electrical connectors. The fretted surface is examined using scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS) analysis to assess the surface profile, extent of fretting damage and elemental distribution across the contact zone and then compared to the capacitance values. The results exhibit that with the increase of the fretting cycles or the vibration frequency, the characteristic value of the wear debris between the contacts of electrical connector gradually increases and the wear is more serious. Measured capacitance values are consistent with SEM and EDS analysis.
