| Abstract: |
| With excellent mechanical properties, high material strength, excellent corrosion resistance and good biocompatibility, titanium alloy materials are widely used in aerospace, national defense, military affairs, biomedicine and other key fields. However, due to the high friction coefficient, unstable friction coefficient, poor wear resistance and high chemical activity of titanium alloy material, its service performance, service life and application range are seriously reduced. In recent years, with the advantages of reducing the actual contact area and storing wear debris, surface texture technology has been proved to be an effective method to improve the tribological properties between friction pairs, and it is also one of the research hotspots in the field of mechanical engineering and tribology. In this paper, the preparation methods and common types of surface micro-texture and the anti-friction mechanism of micro-texture on surface tribology were summarized. Then, the effects of surface texture types, texture density, structural parameters, alignment angle and other factors on the tribological properties of titanium alloy were discussed. Finally, the research status of tribological properties of titanium alloy under the synergistic effect of surface texture technology, solid-liquid lubricant, coating technology and thermal diffusion technology was reviewed. Compared with only using micro-texture technology for surface treatment, composite treatment technology could further improve the surface hardness of titanium alloy and extend the service life of the texture. Generally speaking, the wear resistance of composite treatment titanium alloy surfaces was significantly better than that of single micro-texture treatment surfaces and untreated surfaces, but the friction coefficient was greatly affected by the working condition. Finally, it was suggested that reasonable design of surface texture could improve the tribological properties of titanium alloy. At present, the surface texture of titanium alloy and more complex shapes of bionic surface textures need to be further studied. The positive effect of surface texture on the tribological properties of titanium alloy is manifested in many aspects, such as storing solid lubricants and greases to provide continuous lubrication or re-lubrication, and improving the fluid effect under liquid lubrication. The synergistic effect of surface texture and surface coating or film system can give full play to the advantages of surface texture and other surface treatment technologies, achieve the effect of friction reduction, and promote the application of titanium alloy surface functionalization. The mechanism of composite lubrication friction reduction under the synergistic effect of the surface texture and thermal diffusion technology is still unclear, and the sequence of the combination of the two technologies will also have different effects on the surface bonding strength and tribological properties of different substrates. Exploring the mechanism and sequence of friction reduction after the combination of the two technologies can better improve the friction properties of titanium alloy surfaces. In order to meet the requirements of aerospace, national defense, military affairs and other key fields, it is necessary to carry out research on the tribological properties of titanium alloy under extreme conditions, further optimize the surface topography of titanium alloy, and further study the relationship between the preparation process of the surface texture of titanium alloy and its structure and properties, improve the application of titanium alloy in the field of tribology, and provide data support for the development of titanium alloy, so as to promote the development of composite treatment technology in the application field of titanium alloy. This paper provides reference value for the study of tribological properties of titanium alloy based on surface micro-texture. |
