镓基液态金属具有无毒、低熔点、低饱和蒸气压、流动性好、热稳定性好，高导热性和导电性等优势，是核工业、航空航天工业、医疗器械领域的某些极端摩擦条件下的理想液态冷却剂和润滑剂。围绕镓基液态金属的润滑性能，综述了镓基液态金属的物理化学性能（润湿性、表面张力、熔点、导热系数）和制备方式，介绍了镓基液态金属的润滑性能特征和相关应用，总结了镓基液态金属润滑性能的影响因素和优化方式。展望了对镓基液态金属作为润滑剂的未来发展趋势。
Gallium-based liquid metal has the advantages of non-toxic, low melting point, low saturated vapor pressure, good fluidity, good thermal stability, high thermal conductivity and electrical conductivity, etc. It is an ideal liquid coolant and lubricant in some extreme friction conditions in the nuclear industry, aerospace industry and medical equipment field. Based on the lubrication performance of gallium-based liquid metal, the physical and chemical properties (wettability, surface tension, melting point, thermal conductivity) and preparation methods of gallium-based liquid metal were reviewed. The lubrication characteristics and related applications of gallium-based liquid metal were introduced. The influencing factors and optimization methods of gallium-based liquid metal lubrication performance were summarized. Finally, the future development trend of gallium-based liquid metal as lubricant is prospected.
