在过去的50年中,高级热发动机内的温度一直在提高。新一代的发动机将要求耐1000℃或更高温度的润滑剂。其中最重要的应用之一是用于推进燃气轮机上蓄热室的密封件。另外的重要应用有用于陶瓷滚柱轴承的保持架、高级喷气发动机的控制表面和用于工作温度达1650℃的涡轮冲压式喷气发动机推进系统中的可变截面喷管。对于这些应用将必须设计出一些润滑方式。 目前已研制出的高温固体润滑剂有银
In the past 50 years, the temperature in advanced thermal engines has been rising. The new generation of engines will require lubricants resistant to temperatures of 1000 ° C or higher. One of the most important applications is the seal used to propel the regenerator on the gas turbine. Other important applications are cages for ceramic roller bearings, control surfaces for advanced jet engines and variable cross-section nozzles for turbojet jet propulsion systems operating at temperatures up to 1650 ° C. For these applications it will be necessary to design some lubrication methods. Has developed a high temperature solid lubricant silver
