MAGNETIC PARTICLE TESTING


 

 

 

 

 

 

 

 

 

 

  • Magnetic  particle  testing  is  a  non destructive  testing  method  for  detection  of surface  and  near  surface discontinuities  in ferromagnetic materials.
  • It is one of the most widely utilized NDT methods since it is fast and relatively easy to apply and part surface preparation is not as critical as it is for some other methods.
  • This method uses magnetic fields and small magnetic particles (i.e. iron filings) to detect flaws in components.
  • The only requirement from an inspect ability standpoint is that the component being inspected must be made of a ferromagnetic material (a materials that can be magnetized) such as iron, nickel, cobalt, or some of their alloys.
