Abstract: The influence of temperature on micro-friction at point contact was studied on the basis of analysis of micro interfacial friction. Based on Towle's experimental relationship between sheer strength and temperature and the theory of thermal effect on mechanical properties of material, the relationship between the friction force and temperature is deduced. Theoretical analysis shows that the friction decreases as the temperature increases when the interfacial temperature is lower than the material's Debye temperature. Theoretical calculation and experimental results of atomic force microscopy show the same trend, indicating that the theory and the method presented in this paper is feasible.
