Do you want to carry out an acid corrosion analysis of your materials
What is acid corrosion analysis
Thecorrosion analysis in acidic environments aims to assess the resistance of a material or assembly when exposed to an acidic environment (for example: hydrochloric, sulfuric, nitric acid, etc.). This type of analysis is particularly critical for sectors exposed to aggressive chemical environments.
The electrochemical characterization and corrosion analysis in acidic environments can be applied to many industrial sectors, fromaerospace to cosmetics, includingenergy and medical devices.
Analytical techniques for acid corrosion analysis
Among the approaches used to analyze corrosion in acidic environments, the first is to carry out immersion tests.
The second approach is based on electrochemical tests in acidic media, such as linear polarization, corrosion potential measurement or electrochemical impedance spectroscopy (EIS).
These techniques make it possible to monitor in real time the behavior of a material when exposed to acid attack, while providing quantitative data on corrosion rate and mechanisms.
Finally, post-exposure surface analysis can be carried out to deepen understanding of the phenomenon. SEM-EDX is used to characterize damaged areas, XPS to identify the chemical species formed on the surface, and techniques such as FTIR or X-ray diffraction (XRD) make it possible to analyze deposits or corrosion products.
