Cyclic voltammetry: study of oxidation and reduction reactions
Cyclic voltammetry is an electrochemical analysis technique used to study the oxidation and reduction mechanisms of materials.
It involves applying a variable voltage to an electrode while measuring the current generated, thereby revealing the chemical reactions that occur.
Electrochemical impedance: characterization of interfaces and material properties
Electrochemical impedance is a non-destructive method that analyzes the properties of interfaces between a material and its electrochemical environment.
By applying an alternating signal, it measures a system’s resistance and ability to conduct charge. It is particularly useful for assessing the stability of protective coatings and the durability of biomaterials, such as medical implants, by providing valuable insights into long-term mechanisms.
Polarization curves: determining the corrosion rate
Polarization curves are used to assess the corrosion resistance of materials.
By applying a controlled variation in voltage and measuring the corresponding current, this method makes it possible to determine the corrosion rate and identify the electrochemical reactions involved.
It is widely used to optimize material selection and anti-corrosion coatings in aggressive environments.

Rapid and accurate analysis of metal corrosion through electrochemical characterization
The most suitable electrolytic medium is selected for your application, whether for marine, industrial, or medical environments. This tailored approach ensures relevant and reliable results.
Our electrochemical characterization analysis also make it possible to observe the shift in corrosion potential toward positive values, indicating surface passivation. This phenomenon is a clear sign of improved corrosion resistance of the material.
For which electrochemical environments?
The electrochemical interactions of materials occur in various natural or industrial environments:
Aqueous media, such as seawater, promote phenomena such as galvanic corrosion due to the presence of ions.

Electrochemical interactions and their effects on materials
Analyzing the electrochemical interactions of materials makes it possible to master complex phenomena that influence their performance and durability.
For example, corrosion, which refers to the degradation of metals through electrochemical reactions (such as rust formation), is a major issue in the construction and aerospace sectors.
Conversely, some materials, such as aluminum, benefit from passivation, where a protective layer limits these reactions, providing increased resistance.
Redox reactions (reduction-oxidation) play a central role in energy technologies, while electrodeposition is widely used for metal plating and improving surface properties.

An electrochemical analyzer is a laboratory or industrial device used to measure and analyze the electrochemical properties of materials and systems. It generates, controls, and records electrical signals (current, voltage, impedance) to study chemical reactions and the phenomena occurring at the interface between a material (electrode) and an electrolyte.
Electrochemical impedance is an analysis used to measure the response of an electrochemical system when it is subjected to an electrical perturbation, such as an alternating current or voltage.
It makes it possible to characterize the properties of the interfaces between a material and an electrolyte by evaluating parameters such as charge-transfer resistance and electrochemical capacitance.
This method is widely used to diagnose material performance in electrochemical environments and understand reaction mechanisms.
Many materials are concerned by electrochemical impedance. Metals and alloys (steel, aluminum) are analyzed for their corrosion resistance, while battery materials (graphite, lithium oxides) are used to optimize their performance. Protective coatings (paints, varnishes) are evaluated to prevent degradation, and conductive polymers (PEDOT, polyaniline) are assessed for their conductivity and stability. Finally, biomaterials (titanium alloys) are studied for their biocorrosion. This versatility makes electrochemical impedance a key tool in energy, materials protection, and biomedical devices.
The analysis of an electrochemical deposition bath is essential to ensure a uniform deposit, optimize process performance, and prevent defects that could compromise the quality and durability of the coating. It involves checking the chemical composition by controlling the concentrations of the metal ions responsible for deposition, the additives (levelers, inhibitors), and any impurities that could affect the process. Electrochemical properties are also measured to ensure precise control of the reactions. Finally, parameters such as pH, temperature, and bath conductivity are monitored to maintain stable and efficient conditions, reducing defects and improving coating durability.
