Abstract:

Traditional self-lubricating composites demonstrate excellent tribological properties through multiphase synergy, yet they face dual challenges of insufficient mechanical strength and high-temperature oxidation failure. The former restricts their load-bearing capacity, while the latter induces kinematic stagnation as a result of excessive oxidation film growth. A new strategy based on oxidation regulation can effectively enhance the comprehensive performance of composites by inducing the in-situ generation of specific oxidation products or structures during the friction process. By systematically reviewing the current research status and problems faced by high-temperature self-lubricating materials, three types of oxidation regulation pathways are mainly expounded, namely selective formation of easily sintered oxides, in-situ construction of surface textures, and autonomous generation of lubricative phases, so as to establish dynamic lubrication mechanisms. These findings provide theoretical foundations and technical benchmarks for developing self-lubricating materials with excellent mechanical strength, tribological properties, and oxidation resistance.
