镍基高温合金广泛应用于航空发动机、化工、船舶等领域，是一种典型的难加工材料。为了满足航空发动机特殊工况要求，进一步提高其表面加工质量和加工效率，研究人员开展了诸多理论研究和工艺探索。在概述镍基单晶高温合金和镍基多晶高温合金的发展及其材料特性的基础上，总结了国内外学者在镍基高温合金磨削去除机理、表面完整性、工艺特性等方面的主要研究成果，并对其发展趋势进行了展望。

Nickel?based superalloys, as typical difficult?to?machine materials, are widely used in aerospace engines, chemicals, ships, and other fields. To meet the special working conditions requirements of the aero?engines, and further improve the surface machining quality and processing efficiency, relevant researchers have carried out many theoretical studies and process explorations. The development of nickel?based single crystal superalloys and polycrystalline superalloys, and their material properties were firstly reviewed. Then the main research results of domestic and overseas scholars on the grinding removal mechanism, grinding surface integrity, and process characteristics of nickel?based superalloys were summarized, and their development trends are prospected.
