Abstract: The surface coating and decoration of nano-metal materials is a new research field in nano-science. The coating nano-metal materials are prepared by physical adsorption, suface deposition, arc discharge, plasma polymerization，laser CVD and emulsion polymerization. The coating structure is characterized by direct image of TEM and indirect analysis of component. The applications of coating nano-metal material include tough ceramic, bimetallic powder and non-linear optics property. etc.
