What FPI and Passivation Equipment Do

As popular and proven testing methods, FPI and passivation are ideal for improving manufacturing processes such as quality control and preventing equipment failures.

The Purpose of FPI Systems

Your team can use FPI to look for forging or casting defects on newly manufactured products. The passivation process is also ideal for identifying fatigue cracks and other signs of wear on in-service components that are invisible to the naked eye. FPI is effective for testing nonporous surfaces. These systems can handle metallic or nonmetallic, conductive or nonconductive, and magnetic or nonmagnetic materials.

The FPI Process:

  • Application: The system coats the test item with non-damaging fluorescent liquid.
  • Penetration: The fluid penetrates any surface-breaking discontinuities.
  • Removal: The equipment removes any excess penetrant fluid from the test item.
  • Inspection: The system performs a careful inspection using ultraviolet light.

The Purpose of Passivation Systems

Passivation systems for surface contamination removal use a chemical acid solution, such as citric or nitric acid, to strip excess iron from stainless steel. This process involves immersing parts and components into an acid bath for as much as two hours, then rapidly drying them. This practice promotes the formation of a thin, hard and protective chromic-oxide layer that provides additional corrosion resistance.
