Key components of high-end equipment are often exposed to harsh wear， corrosion or high-temperature environments， thus requiring higher wear resistance， corrosion resistance and high-temperature resistance. As one of the most promising surface engineering technologies at present， thermal spraying technology can be widely applied to many key components of high-end equipment to achieve the purpose of improving their surface performance. Nano thermal spraying technology is an important means to effectively combine nanomaterials and thermal spraying technology to achieve material surface modification. It is also an effective solution to extend the service life of aircraft， ships， and other high-end defense equipment in extreme environments. Nanostructured powder re-granulation technologies enable precise control over the phase composition and microstructure of thermal spray feedstocks at the nano-micro scale. This facilitates the fabrication of nanostructured coatings with tailored properties to meet diverse surface performance requirements for critical components in advanced equipment. This paper briefly summarizes the development status of nanostructured coatings with different functional orientations prepared by thermal spraying at home and abroad in the recent decade， mainly including nanostructured wear-resistant and corrosion-resistant ceramic coatings， nanostructured thermal barrier coatings， nanomodified MCrAlX alloy coatings， nanomodified WC-Co based cermet coatings and nanostructured environmental barrier coatings， etc. The results show that nanostructured and nanomodified thermal spray coatings have a very good potential to be applied on key components of high-end equipments， which can be used to meet the various surface properties required by key component of high-end equipment. key components of high-end equipment have very broad application prospects. To realize the wide application of nanostructured coatings， further research work needs to be carried out in the future in the areas of practical engineering application research， marine environmental service， marine biofouling， advanced powder preparation technology research， and high-performance powder industrialization.
