航空发动机用镍基高温合金涡轮叶盘修复再制造方法研究进展综述

In recent years, superalloys have been widely used in aero-engines. In particular, Ni-based superalloys with higher strength, good corrosion resistance and oxidation resistance are currently the most widely used. This article introduces the application and development status of Ni-based superalloys in aero-engines. Meanwhile, the development of superalloys at home and abroad and the types of superalloys used in different parts and parts of aeroengine are specifically understood. In addition, based on the analysis of the repair remanufacturing of the failed blade, this paper also introduces the research situation of the welding repair remanufacturing and additive repair remanufacturing for the damaged and failed parts of aero-engine at home and abroad.
