The structure and wear properties of the nitrogen-doped TiO_(2-x)N_x films on brackets

To evaluate the biologic wear properties of the nitrogen-doped TiO2-xNx films on brackets.To produce the nitrogen-doped TiO2-xNx films on the surfaces of stainless steel metal brackets by the method of radio frequency magnetron sputtering.The microstructure and the biologic wear properties of the nitrogen-doped TiO2-xNx films were observed by scanning electron microscopy,X-ray diffraction and type UMT-2MT friction-abrasion testing machine.Results: showed that the microstructure of the nitrogen-doped TiO2-xNx films is sharp titanium mineral,nanometer level and uniformly dense structure;the nitrogen-doped TiO2-xNx films perform good wear and low-friction properties under these conditions which are dry friction,artificial saliva solution and Hank's solution.
