由于碳石墨密封材料具有良好的摩擦磨损性能,因此在航空动密封材料中占有重要的位置。六十年代中期,我们对美国 J57、J75、J69、J79等发动机的各类结构碳石墨密封材料样件进行了全面分析,并同时开始了我们自己的航空用碳石墨密封材料的研制工作。所研制的材
Because carbon graphite sealing material has good friction and wear properties, it occupies an important position in the aerodynamic sealing material. In the mid-1960s, we conducted a comprehensive analysis of various structural samples of carbon graphite sealing materials for engines such as J57, J75, J69 and J79 in the United States, and started the development of our own aviation carbon graphite sealing materials. The developed material
