航天飞行器和高效能发动机对润滑剂的热氧化稳定性有很多严格的要求,因此,研制一种新的润滑剂——固体润滑剂势在必行.某些固体能起润滑作用,但是,已知的单一固体润滑剂不能适用于整个的轴承/密封温度范围.为适用于最高工作温度,需要预先采用一些新技术.因此,着重研制能自身润滑的复合材料,包括两种或多种固体润滑剂,以便用于宽广的温度范围.有两种典型固体润滑 Aerospacecraft and high-performance engines have many strict requirements on the thermal oxidative stability of lubricants, so developing a new type of lubricant, solid lubricants, is imperative. Some solids can lubricate but, Known single solid lubricants can not be applied to the entire bearing / sealing temperature range. Suitable for the highest operating temperature, the need to advance the use of some new technologies. Therefore, the focus on the development of self-lubricating composite materials, including two or more solid lubricants For use in a wide range of temperatures There are two typical types of solid lubricants
