TESTS ON MATERIALS
Corrosion tests are carried out on finished or semi-finished products. These make it possible to highlight any manufacturing defects or to assess the corrosion resistance of a product.
The analysis of materials mainly consists in determining their chemical composition as well as their structure. The different techniques used are: metallography, EDX analyzes with SEM, spectrometric analyzes (ICP-OES; Infra Red, ICP-MS);
Study, exepertises, research and development
Th e different areas in which we work allow us to have a global view of the industries. This in-depth knowledge of many areas is a major asset for the client who calls on our services.
CORROSIOn resistance tests
The salt spray simulates a marine atmosphere. This test is used to assess the corrosion resistance of parts or assemblies.
test with sulfur agents (thioacetamide) or synthetic sweat
Climate TestsClimatic tests make it possible to simulate specific atmospheres: relative humidity, temperature, cycles, etc.
Ultra violet AGING
Characterization of mechanical properties
microdurety vickers (HV) GFS FG
Microhardness measurements allow:
check the homogeneity of a material between the core and the surface of the sample
- to check the effectiveness of heat treatments (quenching, tempering, age hardening, annealing, etc.)
- hardness gradient; control of the hardnesses obtained after cementation, nitriding or carbinitriding.
Shore a or d hardness tests
The Shore hardness scale measures the hardness of elastomers, certain plastics, leathers and woods.
Shore A: for soft materials
Shore B: for hard materials
Examples: evaluating the aging of seals in watchmaking
Mechanical tests can be dynamic or static:
- tensile test
- compression test
- fatigue test,
- creep test
They can be produced on wires, bars or strips cut in the form of test specimens.
You will find below some examples of tests carried out in our laboratory.

SITE ANALYSIS : PORTABLE XRF ANALYZER
DETERMINATION OF THE CHEMICAL COMPOSITION
SEM analyzes by EDX microprobe
Spectrometric analyzes: by spark, ICP and infra-red (IR)
Determination of the chemical composition: brasses, steels, stainless steels, special alloys, etc.
Determination of the carbon and sulfur content.

Ductile fracture facies of a cast iron
- Visual examination, problem analysis: definition of the problem.
- Examination of failure facies and determination of failure mode: brittle or ductil
OPTIMIZATION AND IMPROVEMENT OF PROCESSES
We can guide you in the choice of materials :
Some exemples : - Optimization of welding parameters : temperatur, time,... - Material compatibility : avoid corrosion phenomena
