Pure titanium as a biological material, low density, good mechanical performance, strong corrosion resistance, good biology compatibility, so it is widely used in the field of oral medicine. However, pure titanium as the material of denture, poor wear resistance, color appearance, susceptible to fluoride corrosion.
The academic topic related research has been conducted on the plasma nitriding / titanium nitride coating composite surface treatment, surface properties of titanium castings of biological safety, fungal adhesion properties and clinical application effect, experiment is mainly through the potentiodynamic polarization technique and ion release experiment was conducted to observe the effect of composite surface treatment of titanium castings in corrosion resistance of fluorine environment the application of dynamic.
