As system of a serial of technologies and engineering activities, remanufacturing aims at restoring and rebuilding waste machinery through advanced technologies and industrialized measures under the direction of the product total life cycle theory. With the development of surface engineering, nano-surface engineering has beenone subject of intensive studies. In addition, nano-surface engineering has become an important means for property reforming and promoting of remanufacturing parts. Many low-dimension and nano-size or nano-structure functional coatings, which can improve materials properties evidently, are deposited by new methods. In this paper, some researches about the new achievement and remanufacturing application of the nano-stmctured coatings by different nano-surface engineering technologies in our laboratory were introduced. Especially, nano-structured DLC multi layer coatings by d.c. plasma CVD, nano-composed Al2O3/Ni, SiC/Ni and Diamond/Ni coatings by brush plating,and nano-composed Al2O3/TiO2 coating by plasma spraying were introduced in detail.
