Pure titanium castings surface nitriding

Ti has good mechanical properties, chemical stability and biocompatibility, have been widely used in aerospace, marine, military and biomedical fields. Pure titanium in oral medicine is mainly used for making denture, crown and fixed bridge, orthodontic bracket,implant and titanium porcelain etc..

  Titanium  is self passivation of metal, a layer of stable and dense oxide film formed surface at room temperature, so it has good corrosion resistance. But pure titanium low hardness, wear resistance is poor, pure titanium prosthesis to function in oral BOC,titanium oxide films on the surface of friction force, shearing force under stress, prone to scratches and wear, dental caries preventive agents such as fluoride toothpaste, gel on the film also has a certain role in bad breaking.
