You would like to carry out a Potensiostat analysis in your laboratory

A potentiostat is an electrochemical measuring instrument used to study the behaviour of a material subjected to electrochemical corrosion. It is a key tool in testing the performance of anti-corrosion coatings, particularly in wet, saline or chemical environments.

Potensiostat

What is a potentiostat used for?

It controls the voltage (potential) between a working electrode (the material under test) and a reference electrode, while measuring the current flowing between the working electrode and an auxiliary electrode. This makes it possible to observe and quantify :

corrosion speed

the resistance of a coating to oxidation

the formation of passive layers

the kinetics of electrochemical reactions

Its use in anticorrosion coatings

In anticorrosion coatings, it is used for

Testing the effectiveness of an anti-corrosion treatment

Drawing polarisation curves

Measuring corrosion current

Analyse polarisation resistance and electrochemical impedance (EIS)

our electrochemical analysis services

Measurement of the free potential (OCV) to evaluate the spontaneous electrochemical behavior of a metal in a given medium (water)

Galvanic coupling testing in order to analyze the interactions between two metallic materials to identify differential corrosion risks (ex: Zinc vs Steel)

Characterization of protective properties: barrier properties, porosity, water permeability, delamination, filamentary corrosion... ,

Determination of the corrosion rate (LSV) in order to know the corrosion rate (mm/year) in various environments (salt water, pure water, inhibitor presence)

Measurement of corrosion potential (polarization curves)

Development of specific electrochemical tests (cathodic delamination, ACET, corrosion at the edges ...)

FAQ

What types of samples can be analysed?

We analyse raw or treated metal parts, organic or metallic coatings deposited on a support, or standard test coupons. The sample must be suitable for an electrochemical cell.

Can specific environments be simulated?

Yes, the analysis can be carried out in different electrolytes (NaCl, acidic or basic media, custom solutions) to mimic your real industrial conditions.

What is the difference with a salt spray test?

The salt spray test is a global, visual and normative ageing test (ISO 9227), while the potentiostat provides numerical and dynamic data on electrochemical behaviour. The two approaches are complementary.

Is this a standardised method?

Yes, there are several standards governing electrochemical analysis:

  • ASTM G5 / G59 / G102
  • ISO 17475
  • ISO 16773 (EIS)

We can adapt the protocols to your requirements.
