Increasing the service life of friction linings and engine bearings is an important development direction to improve the reliability of key automotive components. This subject uses the characteristics of small size activity and high specific surface area of inorganic oxide nanoparticles such as silica, zirconium dioxide, and alumina to improve the interface compatibility between the nanoparticles and the polymer matrix, thereby realizing the nanoparticles. The uniform dispersion in the liquid phase system solves the difficult technical problem of dispersing nanoparticles in organic resins. By studying the composition of composite nanoparticles with different structural characteristics, the control method of micro-nano particles, and the interface strengthening mechanism of the composite structure, a high performance is developed. Nano-composite friction materials and low-friction coating materials increase the service life of friction linings and bearings. The research results of this topic are of great significance to the industrial technology upgrade of the brake linings and engine bushes.
