N2 - The tribological properties of the couple of three-dimensional needled C/SiC composite and 30CrSiMoVA were investigated on MM-1000 II friction testing machine.The wear mechanisms and phase transformation were analysed with SEM, XRD, EDS, thermodynamics, and finite element simulation of braking temperature field. The results show that, with the increase of the initial braking speed, the average friction coefficient of the couple of three-dimensional needled C/SiC composite and 30CrSiMoVA decreases, the temperature of friction surface increases, and the linear wear rate of three-dimensional needled C/SiC composite and 30CrSiMoVA tended to increase. When the initial braking speed is greater than 15m/s, the maximum temperature on the friction surface exceeds 560 °C. Besides, Fe3C, Fe3Si, FeO, γ-Fe2O3and α-Fe2O3 was found, which was supposed come from the reactions of Fe, SiC, Si and O2. This reaction together with abrasive wear adhesive wear and fatigue wear, accelerate the wear of materials.
