Surficial water adsorption and interfacial water condensation as natural phenomena that can alter the contact status of the solid interface and tribological performances are crucial in all length scales, i.e., from earthquakes to skating at the macroscale level and even to micro/nano-electromechanical systems (M/NEMS) at the microscale/nanoscale level. Interfacial water exhibits diverse structure and properties from bulk water because of its further interaction with solid surfaces. In this paper, the evolutions of the molecular configuration of the adsorbed water layer depending on solid surface chemistry (wettability) and structure, environmental conditions (i.e., relative humidity and temperature), and experimental parameters (i.e., sliding speed and normal load) and their impacts on tribological performances, such as adhesion, friction, and wear, are systematically reviewed. Based on these factors, interfacial water can increase or reduce adhesion and friction as well as facilitate or suppress the tribochemical wear depending on the water condensation kinetics at the interface as well as the thickness and structure of the involved interfacial water.

表面水吸附和界面水凝结是自然现象，可以改变固体界面的接触状态和摩擦学性能，在所有长度尺度上都是至关重要的，例如，从地震到宏观尺度上的溜冰，甚至是微/纳米机电系统（ M / NEMS）。界面水由于与固体表面的进一步相互作用而具有与散装水不同的结构和性能。在本文中，取决于固体表面化学（润湿性）和结构，环境条件（即相对湿度和温度）以及实验参数（即滑动速度和法向载荷）的吸附水层的分子构型的演变以及它们对摩擦性能的影响，例如附着力，摩擦力，和磨损，得到系统地审查。基于这些因素，界面水会增加或减少附着力和摩擦力，并促进或抑制摩擦化学磨损，具体取决于界面处的水冷凝动力学以及所涉及界面水的厚度和结构。
