润滑失效已逐渐成为限制空间机械系统寿命的主要因素之一。 综述了空间润滑方法,分析了空间液体润滑的利弊以及蠕爬流失产生的机理。 讨论了抑制润滑剂蠕爬的方式,展望了表面织构技术在控制液体空间润滑剂蠕爬流失研究中的应用前景。

Lubrication failure has become one of the main reasons that limit the lifetime of mechanical system in space. Brief review of several methods in space lubrication was presented. Advantages and disadvantages of liquid lubrication were introduced and the mechanisms of liquid lubrication migration was demonstrated. Some effective anti-creep methods were introduced. Application outlook of surface texture in preventing the liquid lubrication migration in space was proposed.
