| Abstract: |
| In the field of aerospace, high-end machine tools, deep-sea exploration and rail transport and other mechanical equipment, the study of surface tribological properties of metal parts mainly focuses on coatings, weaving and solid lubricants. Due to their wide range of applications in these fields and their complex and various working conditions, a single friction structure is difficult to meet the needs of friction and wear of components in harsh environments. Therefore, the main direction of the current research is to build multiple types of friction structures through the synergistic effect of coatings, textures and solid lubricants. By studying the combination of different coatings, fabrics and solid lubricants, the diversification and optimization of friction structures can be effectively realized to enhance the friction and wear reduction effect on the parts surface, thus prolonging the service life of the parts and guaranteeing their reliability under complex working conditions. In this paper, according to the friction and wear-resistant structural forms of different summarized five types of structural forms:Structures prepared by homogeneous mixing and sintering of matrix and lubricant powders are called matrix mixed lubricant type; Structures in which the lubricant filled metal surfaces become textured called textured composite lubricants type; Structures in which the lubricant dopes inside the metal surface coating called coating doped lubricants type; Structures prepared on metal surfaces using surface texturing and coating techniques called textured composite coatings type. The article combines the design and preparation methods of these five types of structures in detail, and at the same time discusses the friction and wear reduction mechanisms of coatings, textiles and solid lubricants in the friction process under the synergistic effect of each other. In addition, the important protective role played by multiple types of coatings within the friction structure, the influence of texture shape parameters on the friction structure's friction reduction and lubrication effect, the effect of mixing different types of solid lubricants in the matrix, within the coatings, and within the texture are analyzed, and the formation of lubricating films at the friction interface by various types of friction structure's solid lubricants is illustrated. The article also summarizes the advantages and disadvantages of various types of friction structures in practical applications, and also highlights key scientific issues such as the interaction of coatings, weaves and solid lubricants at the friction interface (anti-oxidation and anti-detachment within the solid lubricant mix; solid lubricant-filled weaves and re-supplementation; comparison of the ways in which the solid lubricant is precipitated; determination of the appropriate weave dimensional parameters; high economic costs due to the weave finishing process; coating coating and filling process. The key scientific issues are the compatibility and uniform distribution of solid lubricants with coatings and the adaptability of friction structures under multiple operating conditions. Finally, the prospect of developing new environmentally sustainable friction materials that can reduce or replace the use of hazardous materials, intelligent lubrication coatings that can realize intelligent and adaptive lubrication effects to take on complex and critical lubrication effects, and multifunctional integrated structures that can realize self-repairing, corrosion-resistant, and other properties is envisaged. |
