Cu-graphite composites (CGCS) are important in friction applications, yet their performance is limited by the weak bond of Cu and graphite. This research explores the integration of Ti₃AlC₂ into CGCS to enhance their tribological properties. The impact of sintering temperature on various aspects including microstructure, density, hardness, electrical conductivity, interfacial properties, and tribological behavior of Cu-graphite-Ti₃AlC₂ composites (CGTCS) fabricated by spark plasma sintering (SPS) was studied. Results indicate mutual diffusion between Ti₃AlC₂ and Cu during sintering, leading to metallurgical bonding. Moreover, titanium atoms originating from Ti₃AlC₂ undergo a reaction with carbon atoms present on the graphite surface, facilitating enhanced bonding of Cu and graphite. CGTCS exhibit promising lubrication performance across different sintering temperatures, with friction coefficients ranging from 0.15 to 0.25. Initially, the wear rate decreases, then increases with rising sintering temperature. Optimal tribological properties are achieved at 980 °C, the average friction coefficient and wear rate are 0.18 and 4.82×10_-6 mm₃/N.m, respectively.
