Abstract: Compared with traditional microstructured ceramic coatings, nanostructured ceramic coatings usually exhibite improved properties such as interface bonding strength, fracture toughness and wear resistance, and have thus been utilized in many military and civil industries.However, there are several characteristics and difficulties in fabrication of the nanocoatings.In addition, the fabrication techniques may bring direct influence on microstructures and properties of the coatings.This paper describes some fabrication methods of nanostructured ceramic coatings in detail.
