Objective： in order to smooth the titanium surface with antimicrobial properties, use the method of silane coupling the nanosize silver particles coating on the titanium plate, and its physical and chemical properties were analyzed. Method：the experimental group for modified titanium silver nanoparticles,the control for smooth titanium plate,each 10 pieces. Scanning electron microscope observation of titanium plate surface morphology, the nano silver particle morphology, size and adhesion on titanium plate; X-ray energy spectrum and titanium plate line scanning analysis on composition of each element; X-ray photoelectron spectroscopy quantitative analysis of the modified titanium surface elements. Result： macro- scopic observation of the modified nanometer gum titanium surface is smooth, basal surface by scanning electron microscopy （sem） with silver nanoparticles, diameter of dozens of nanometers, form into a circular or cylindrical, part of the nanoparticles reunion together; Titanium surface X-ray photoelectron spectroscopy analysis results show that the experimental group con- taining Ti titanium surface, Ag, C, four elements, including the percentage of Ag atoms is 5.3 %, and the silver elements com- bine to 367.9 ev. Conclusion：the method of this experiment by silane will deposition on the surface of titanium silver nanoparticles, this method is simple, no special equipment, is of strong maneuverability.
