You would like to carry out corrosion analysis in an acid medium on your materials
What is a corrosion analysis in an acid medium
Corrosion analysis in an acid medium aims to evaluate the resistance of a material or assembly when it is exposed to an acidic environment (for example: hydrochloric acid, sulphuric acid, nitric acid...). This type of analysis is particularly critical for sectors exposed to aggressive chemical environments.
Electrochemical characterization and impedance measurement can be applied to many industrial sectors, from aeronautics to cosmetics, including energy and medical devices.

ANALYTICAL RESSOURCES
- Among the approaches used to analyse corrosion in an acid environment, the first consists of carrying out immersion tests. The material is immersed in a defined acid solution (concentration, temperature, duration), then mass losses, visual alterations or the formation of corrosion products are observed. These tests can be carried out in accordance with standardised norms (ASTM, ISO, etc.) or adapted to specific customer conditions.
- The second approach is based on electrochemical tests in an acidic medium, such as linear polarisation, corrosion potential measurement or electrochemical impedance spectroscopy (EIS). These techniques enable the behaviour of a material in the face of acid attack to be monitored in real time, while providing quantitative data on the speed and mechanisms of corrosion.
- Finally, post-exposure surface analysis can be carried out to gain a deeper understanding of the phenomenon. SEM-EDX is used to characterise damaged areas, XPS to identify chemical species formed on the surface, and techniques such as FTIR or X-ray diffraction (XRD) to analyse deposits or corrosion products.
