Nanometer materials possess many excellent properties. Using thermal spraying technology to prepare nanostructure coating is an effective method for applying nanometer materials. The preparation methods of spraying materials for nanostructure coating, including liquid feed, nanometer powders and nanometer powder-filled cord wire, were presented. The kinds of nanostructure coatings including nanostructure ceramic coating, nanostructure ceramic-metal composite coating and nanostructure metal coating, were introduced. The methods for preparing nanostructure coating, coating structure and properties were also introduced, and the present problems were discussed on nanostructure coating prepared by thermal spraying method, and the development and application prospects of nanometer thermal spraying technology were forecasted.
