Corrosion analysis

Corrosion is a major cause for failures, and it is becoming more and more critical for reliability. Corrosion analysis methods can give you extra information about the corrosive environment your products are used in. 

We offer corrosion analysis for your devices as well as corrosive environment monitoring service!

Corrosion analysis and test methods


We offer analysis of the corrosion and corrosion products with and optical microscope. For more detailed analysis Scanning electron microscope (SEM) with Energy-dispersive X-ray spectroscopy (EDX) can be used as well as X-ray diffraction (XRD) analysis. EDX and XRD give information about the composition of the corrosion products.

For bare copper or silver samples, we offer coulometric reduction method to get thicknesses and compositions of different layers of the formed corrosion products. Cross section with SEM analysis offers a way to see how deep the corrosion has reached.

Corrosion test methods

Mixed flowing gas (MFG) testing

  • Single gas testing or combination of several different corrosive gases
  • Several test standards available
  • Testing of components and whole devices
  • Electrical measurements availabel during testing

Salt spray testing

  • Continuous salt spray testing
  • Cyclic tests
  • Electrical measurements available during testing

Flowers of sulphur testing

  • Testing with high sulphur athmosphere
  • Can be combined with chlorine exposure
  • Designed especially for for printed circuit boards and creep corrosion studies
  • Especially effective for silver
