7.1 前言 固体润滑膜已经应用在人造卫星、火箭和飞机的重要部件上。例如,航天飞机的主发动机通过万向架机构实行助推力的方向控制,这种万向架轴承的润滑就使用着二硫化钼系的固体润滑膜。在新近问世的喷气发动机中,作为叶轮翼和叶轮组装件的润滑使用的也是固体润滑膜。图7.1是叶轮翼的照片,在其燕尾槽部位所看到的黑影就是固体润滑膜。预料今后固体润滑膜的应用范围必 7.1 Introduction Solid lubricant films have been used in important parts of satellites, rockets and aircraft. For example, the space shuttle’s main engine is controlled by a gimbal mechanism to boost the direction of the boost. The gimbal bearing is lubricated with a molybdenum disulfide-based solid lubricant film. In the recently introduced jet engine, the solid lubricant film was also used for lubrication of the impeller blades and the impeller assembly. Figure 7.1 is a photograph of the wing of the impeller. The shadow seen in the dovetail slot is the solid lubricant film. It is expected that the range of application of the solid lubricant film in the future must be
