You would like to carry out a study of the corrosion rate of your materials
What is the corrosion rate?
Corrosion rate is a key indicator of how quickly a material (generally a metal) degrades under the effect of its environment. It is usually expressed in millimetres per year (mm/year) or in loss of mass per unit area and time (g/m²/day, for example).
Electrochemical characterization and the study of the corrosion rate can be applied to many industrial sectors, from aeronautics to cosmetics, including energy and medical devices.
The FILAB laboratory can help you study the corrosion rate of your materials
In many industrial sectors, materials are subjected to aggressive environments: humidity, chemical agents, extreme temperatures, salt spray, mechanical stress, etc. Corrosion is not always immediately visible, but its consequences can be critical: loss of performance, part failure, contamination, production stoppages or regulatory non-compliance.
By studying the rate of corrosion, we can assess a material’s performance in a given environment and predict its lifespan.
Why choose FILAB for the study of the corrosion rate ?
FILAB, a laboratory made up of experts in metallurgy and steelmaking analysis, provides its knowledge and expertise to carry out the study of the corrosion rate and electrochemical characterization of your metal parts.
To support you in the best conditions, the FILAB laboratory is approved Research Tax Credit (CIR) and accredited COFRAC ISO 17025.
our technical resources for studying corrosion rates
Why perform a study of the corrosion rate ?
Evaluate the corrosion resistance of a metal or an alloy
Test the effectiveness of an anticorrosive coating or a paint
Characterize passive films on metal surfaces
Control the degradation of electrolytes, batteries or sensors
Study diffusive, capacitive or resistive behaviors in a system
Encourage innovation and compliance
Meet standards requirements (ISO, ASTM, specific standards for the aeronautical, automotive and medical sectors, etc.)
our electrochemical analysis services
Measurement of the free potential (OCV) to evaluate the spontaneous electrochemical behavior of a metal in a given medium (water)
Measurement of corrosion potential (polarization curves) Potensiostat
Development of specific electrochemical tests (cathodic delamination, ACET, corrosion at the edges ...)
Study of galvanic coupling 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... ,
Impedance measurement to analyse the properties of the interfaces between a material and its electrochemical environment
We work on all types of metallic or coated materials:
- Steel, stainless steel, copper, aluminium, titanium, etc.
- Specific alloys (e.g. aerospace, medical)
- Protective coatings (paint, surface treatment, anodising, etc.)
Yes, we adapt the test conditions to suit your specifications or the environment in which they are actually used:
- Temperature, humidity, pH, ion concentration, presence of chlorides, etc.
- Possibility of accelerated testing (ageing, thermal cycles, controlled atmospheres)
Yes, our laboratory is equipped to characterise surface alterations:
- SEM-FEG coupled with EDX: observation of localised attacks, pitting, cracks, and elemental analysis of deposits or oxides
- Profilometry or roughness measurement: to quantify changes in roughness or loss of thickness
- Optical microscopy: for visual mapping of damaged areas
Exactly. We can compare :
- Several alloys in the same environment
- A material with and without surface treatment
- Different exposure conditions (pH, temperature, concentration, etc.)
The aim is to help you make an objective technical choice or validate a formulation, coating or design.
Yes, thanks to our surface instrumentation, we can :
- Produce post-exposure thickness or roughness maps
- Use SEM coupled with EDX to visualise the distribution of etching or deposits
- Combine these data with spot electrochemical measurements on targeted areas
