title: [Experimental study on the bonding strength between FCVA film and titanium].
abstract: OBJECTIVE
  To study the bonding strength between the FCVA (filtered cathode vacuum arc) film and the titanium substrate.
  
  
  METHODS
  According to the Engineer Manual of Germany (VDI3198), the indentation test was applied to evaluate the bonding strength between the FCVA film and the titanium substrate. The structure of the FCVA film and the interface between the film and the substrate were observed by means of scanning electron microscope(SEM).
  
  
  RESULTS
  The fracture pattern of the film was classified as HF3 at the load of 400N, the bonding strength was enough between the FCVA film and the titanium substrate. SEM photograph showed the thickness of the FCVA film was about 1.2μm equably and the film bonded to the substrate well. CONCLSION: The bonding strength between the FCVA film and the titanium substrate was enough to meet clinical demand.
