Abstract: The anti-friction behaviors of perrhenates of cobalt, calcium and copper were tested in a Universal Micro-Tribotester with ball (Si3N4) on disc (superalloy) at elevated and declined temperature from room temperature to 600℃ or 750℃. Composition of debris and morphologies of the worn tracks were determined by X-ray Diffraction (XRD) and Scanning Electron Microscope – Eneregy Disperive Spectrometer (SEM-EDS), and contact resistance between the worn surface and steel ball was measured by UMT-R1. The results showed that friction coefficient of these perrhenates exhibited certain downtrend with elevated temperature, and perrhenates of cobalt and calcium still showed good lubricity during the declined temperature process. It implied that these two surface films formed at high temperature could be kept to low temperature. So these two perrhenates could be developed as the candidate of solid lubricant for rubbing pairs in variation of temperature.
