Corrosion test

The different corrosion tests

Corrosion test in a controlled gaseous atmosphere

Purpose of this type of corrosion test :
To assess the corrosion resistance of materials or plastics in the presence of gaseous atmospheres containing oxygen, chlorine, fluorine and other corrosive gases, in order to determine its durability under specific conditions of use.

Gaseous atmospheres :

-Oxygen
-Chlorine
-Fluorine
-Other gases

Acid corrosion test

Purpose of this type of corrosion test :
To assess the corrosion resistance of a material (metal, alloy, polymer, etc.) or plastics in the presence of acid solutions, in order to determine its durability under specific conditions of use (for example, in an industrial or food environment, etc.).

A wide range of acids can be used to simulate different stress conditions. Examples include :

-Strong mineral acids: Hydrochloric acid (HCl), sulphuric acid (H₂SO₄), nitric acid (HNO₃)
-Organic acids: Acetic acid (CH₃COOH), citric acid (C₆H₈O₇)
-Other acids: Hydrofluoric acid (HF), phosphoric acid (H₃PO₄)

Our speciality

Fluorine corrosion

Fluorine corrosion tests are rigorous procedures designed to assess a material’s resistance to attack by this highly reactive element. These tests are particularly important in sectors where materials are exposed to corrosive environments rich in fluorine, such as the nuclear, aerospace and microelectronics industries.

Why Test Corrosion with Fluorine?

  • Specific Industries: Industries such as aerospace, nuclear, and microelectronics use materials that must withstand extremely corrosive environments, often rich in fluorine.
  • New Materials: New alloys and composite materials require rigorous evaluations to determine their resistance to chemical attacks, especially by fluorine.
  • Protective Coatings: Fluorinated coatings are increasingly used to protect metal and non-metal surfaces. Fluorine corrosion tests evaluate the effectiveness of these coatings.

Parameters Evaluated During Tests

  • Corrosion rate: Measures the loss of material mass per unit area and time.
  • Formation of corrosion products: Identification of compounds formed on the material’s surface.
  • Microstructure modification: Analysis of the material’s microstructure after fluorine exposure.
  • Coating adhesion: Evaluation of the fluoride coating’s adhesion to the material’s surface.
