WHO ARE WE?

Materials Science Specialist

Founded in 1996 by Dr. A. Benghalem, Métalab is an independent laboratory located in Porrentruy, in the Jura region. Specializing in the study and characterization of materials, Métalab offers its expertise to provide strategic solutions for demanding industries, particularly in materials, machining, and surface treatments.

Material Testing

Corrosion tests are performed on finished or semi-finished products to detect potential manufacturing defects or assess a product's resistance to corrosion. Mechanical tests, on the other hand, are used to characterize the physical properties of materials, such as hardness or elastic stress.

Material Analysis

Material analysis mainly involves determining their chemical composition and structure. Techniques used include metallography, EDX analysis with SEM, as well as spectrometric analyses such as ICP-OES, infrared, and ICP-MS.

Study, expertise, research, and development

The different sectors in which we operate provide us with a comprehensive view of the industries. This diversified expertise is a key asset for our clients, who benefit from solutions tailored to their specific needs.


Material Testing

At Métalab, we conduct various environmental tests to assess the durability of materials. We perform salt spray corrosion tests, sulfur agent tests such as thioacetamide, synthetic sweat tests, climatic tests, and UV aging analyses. These methods allow us to simulate different usage conditions and identify the performance of materials in diverse environments.

Salt spray

The salt spray test simulates a marine atmosphere by exposing parts to a mist of saline solution in a testing chamber. This method evaluates the corrosion resistance of parts or assemblies by replicating the effects of exposure to salty, humid air, commonly found in marine environments.

Tests with sulfur agents (thioacetamide) or synthetic sweat

The sulfur agent test simulates aggressive environments, such as those found in certain industrial settings. The synthetic sweat test, on the other hand, replicates the conditions experienced by components in direct contact with the skin.

Climatic testing

Climatic tests replicate specific atmospheres by controlling parameters such as relative humidity, temperature, and environmental cycles.
UV aging test
UV tests simulate exposure to solar radiation, allowing the evaluation of the photodegradation of polymers.

We combine Vickers microhardness (HV) tests with Shore A or D hardness tests to precisely assess the mechanical properties of various materials. These thorough analyses enable us to deliver solutions tailored to our clients' specific requirements, ensuring the quality and reliability of the materials tested.

Vickers microhardness (HV) gfs fg

Microhardness measurements help control the homogeneity of a material between its core and surface. They are also used to verify the effectiveness of heat treatments, such as quenching, tempering, structural hardening, or annealing. Additionally, these measurements allow for the analysis of hardness gradients and the control of hardness values obtained after processes like carburizing, nitriding, or cementing.

Shore A or Shore D hardness

The Shore hardness scale is used to measure the hardness of elastomers, certain plastics, leathers, and woods. It is divided into two main scales: Shore A, used for soft materials, and Shore D, for harder materials. For example, this method can be used to evaluate the aging of watch seals.

Mechanical tests

Mechanical tests can be classified into two categories: dynamic or static. Among the tests performed are tensile testing, compression testing, fatigue testing, and creep testing. These tests can be conducted on wires, rods, or strips cut into specimen shapes.

Below are some examples of tests conducted in our laboratory.

ON-SITE ANALYSIS: PORTABLE XRF ANALYZER

Material Analysis

We offer a wide range of material analyses to ensure their quality and compliance. With our expertise, we perform precise analyses, ranging from chemical composition determination to microstructural examination. Our services include macrographic examination to observe visible characteristics, fluid analysis to control oils and galvanic baths, and microstructure study to identify phases and detect potential impurities. These analyses allow us to guarantee optimal performance and perfect control of the materials used.

DETERMINATION OF CHEMICAL COMPOSITION

The chemical composition of materials can be determined using EDX microprobe analysis with SEM or spectrometric techniques (spark, ICP, IR). These methods allow for the identification of elements present in brass, steels, stainless steels, and special alloys, as well as measuring the levels of carbon and sulfur.

MACROGRAPHIC EXAMINATION

Micrographic examinations allow for the analysis of the internal structure of materials, including the fiber orientation of cast parts, revealing their texture and homogeneity.

FLUID ANALYSIS

Fluid analysis allows for the control of the quality of oils, galvanic baths, and wastewater to ensure their proper functioning and compliance with standards.

EXAMEN MICROSTRUCTURAL

Microstructural examinations allow for the identification and characterization of a material's microstructure, highlighting its phases, as well as any potential impurities or porosities.

This list is not exhaustive; we also perform layer thickness measurements through micrographic sections, surface roughness measurements (Ra), and determination of crystalline structure (monocrystalline or polycrystalline).
