Abstract For the needs of increasing the application speed of space electrical contact materials, the effect of sliding speed on the current-carrying friction and wear behavior of the AuNi9 (HV of 270.3)/AuAg35Cu5 (HV of 202.3) friction pair was investigated. The experimental results show that with increasing sliding speed from 56.5 mm/s to 194.2 mm/s, the average value of friction coefficient and contact voltage drop of the friction pair increase from 1.1 to 2.0 and 71.8 mV to 132.8 mV, respectively. The square root of pressure drop curve (RMS) value of contact voltage drop also increases from 0.16 mV to 0.76 mV. The research findings show that increasing of sliding speed can reduce the contact stability and cause more material transfer between the friction pair, which results in the increasing of both roughness and wear rate of the brush wear surface from 0.41 μm and 4.7×10^-16m³/(N·m) to 1.2 μm and 1.4×10^-14m³/(N·m), respectively. In addition, micro-zone weld pools are clearly observed on the wear surface of disc after the current-carrying friction at the speed of 194.15 mm/s, which decreases the stability of current-carrying friction of the friction pair.
