title: [Effects of Sol-Gel coating on the corrosion resistance of nickel-chronium alloys].
abstract: OBJECTIVE
  To investigate the effects of Sol-Gel coating on the corrosion resistance of nickel-chronium alloys in vitro.
  
  
  METHODS
  The bond strength of coating-substrate interface sintered at different temperatures (300, 400, 500, 600 degrees C) was tested by scratching method. The Sol-Gel coating was analyzed by scanning electron microscope (SEM), and its corrosion resistance was assessed by a static immersion method.
  
  
  RESULTS
  The bond strength of coating-substrate interface reaches the peak at 400 degrees C. The Sol -Gel coating can apparently inhibit the release of metal ions and improve the corrosion resistance of nickel-chromium alloy.
  
  
  CONCLUSIONS
  Sol-Gel coating can evidently improve corrosion resistance of the nickel-chromium alloy, which has great potential in prospective clinical practice.
