Corrosion and biocorrosion analyses

Analyzing to have a better understanding of corrosion problems

Corrosion and biocorrosion analyses: from the first sign of material failures due to corrosion, ask for analyses in order to observe the phenomenon involved. They will give you a precious help to identify the cause of corrosion problem.

Metallographic, microbiological or physicochemical, these analyses will allow you to evaluate the level of corrosion, to detect or not corrosive bacteria, etc.

Analysis of metallic materials at low and high magnification

Profil de dégradation analyse métallographique Objective

  • Determine the quality of the materials
  • Establish a degradation profile


  • Characterization of the material
    metallurgical quality control of metallic material (microstructure, hardness, grain size, inclusion cleanliness, ferrite content …)
  • Measuring the thickness of a metal or organic coating
  • Uniform degradation
    Electrochemical monitoring – Gravimetric monitoring
  • Localized degradation
    Morphology and degradation profile, measuring depths of attacks, estimate the density of degradations
