大批华命性的系统设计需要新的材杆、加工这些材朴的方法和史透彻地了解其原理。高温材料促进了航空航天推进系统与电力系统的发展。但在今天,材料研究若仍保持过去二、三十年的发展速度,已经不能满足要求了。系统设计师们要求的是革命性的而不是改良性的进展。因此,国家航空航天局刘易斯研究中心(它是该局在材料研究与开发方面一直处于领先地位的单位)正在研究:新材料,加工这些新材料的方法,以及这些材料如何工作的基本原理,以便指导未来的工作。飞机燃气涡轮的叶片、导向叶片和轮盘一直是用镍基合金制造的。目前,为了达到更高的温度,各个实验室都在制造金属互化物及具有隔热涂层的金属基体复合材料与陶瓷基体复合材料,而且在研究固态润滑剂。
A large number of life-saving system design requires new materials, processing these simple methods and history thoroughly understand its principles. High-temperature materials promote the development of aerospace propulsion systems and power systems. However, material research today can not meet the requirements if it still maintains the pace of development in the past two or three decades. System designers demand revolutionary rather than progressive improvements. As a result, the NASA Lewis Research Center, which has been the leader of the Agency in material research and development, is studying the fundamentals of new materials, methods of processing these new materials and how they work so that Guide future work. Aircraft gas turbine blades, guide vanes and roulette has always been made of nickel-based alloys. At present, in order to reach higher temperatures, various laboratories are making intermetallics and metal matrix composites with ceramic matrix composites with thermal barrier coatings and are working on solid lubricants.
