Abstract: Surface engineering has gone through three stages: traditional surface engineering, composite surface engineering and nano-materials surface engineering. The basic methods obtaining the nano-surfaces are gas depositing, surface nano-crystallized and nano-coated. By now the practical nano-materials surface engineering includes the techniques as follows: nano-films depositing, nano-materials thermal spraying, nano-materials electric brush plating, nano-materials self-repaired antifriction, solid lubrication nano-films, nano-materials gluing, nano-materials painting and metal surface nano-crystallized. Nano-materials surface engineering is the key component for advanced manufacturing and remanufacturing engineering, and that provides the technological supports to the development of advanced manufacturing and remanufacturing engineering. Nano-materials surface engineering is significant in promoting the properties and qualities of electromechanical products, decreasing the cost of materials, conserving energy and protecting environments. It is the important development trend for nano-materials surface engineering that enlarging the implementation methods of nano-surfaces, further extending the compounding between nano-materials surface engineering and traditional surface engineering, and broadening the industrial application of nano-materials surface engineering.
