Filiform Corrosion Testing

Applied Technical Services provides clients with filiform corrosion testing. Filiform corrosion occurs under a thin layer of coating in the form of threadlike filaments. We can identify filiform corrosion on metallic surfaces that are covered with an organic film. Based on the unique appearance of fine filament lines, the pattern of the corrosion can be characterized. We test filiform corrosion resistance of metals in compliance with ASTM D2803 and ISO 4623.

Filiform Corrosion is Commonly Discovered On:

  • Aluminum
  • Steel
  • Aircraft Structures
  • Beverage Cans
  • Gaskets
  • Flanges
  • Weld Zones with Organic Coatings
  • Architectural and Automotive Applications

Corrosion can cause large financial losses among the various sectors it affects. In fact, a report released by NACE International estimated that corrosion impacts the United States economy by more than 250 billion dollars. The sectors significantly affected by corrosion include utilities, infrastructure, transportation, and manufacturing.
