Our bespoke surface analysis services and techniques
Our surface analysis services
Surface chemistry is concerned with the surface properties of materials. It enables the chemical properties of surface materials to be modified, if necessary, to give them new properties suited to their use.
Morphology, the three-dimensional study of surfaces, and topography, analysed at macro, micro and nanometric levels, are crucial for optimising industrial manufacturing processes. These analyses help to prevent failures by providing an in-depth understanding of material properties.
Multilayer analysis of material surfaces involves examining several surface layers of a material. This technique is widely used to identify the surface composition of materials.
The surface of a material interacts with its external environment and may encounter chemical contamination or particle pollution as a result of the various stages in the manufacturing process, for example.
The measurement of surface tension determines the force acting on the surface of a liquid, due to the attraction between its molecules. This force is responsible for behaviours such as droplet formation and spreading on surfaces, and enables the surface area of the liquid to be minimised. This measurement is used to understand and optimise liquid-liquid and liquid-solid interactions in various industrial and scientific contexts.
Surface topography analysis is used to optimise the contact, adhesion and durability properties of materials, particularly for coatings, medical devices and aeronautical components. During this surface analysis, the physical characteristics of a material's surface, such as its texture, asperities and overall shape, are assessed.
VSSA analysis is used to determine the specific surface area of a material per unit volume. This analysis is mainly used in the pharmaceutical industry and for characterising materials, particularly porous materials or powders, where chemical reactivity and dissolution are influenced by the specific surface area.

As well as checking the surface cleanliness of the material, the laboratory identifies the pollution in question.
Materials interface analysis is a technique for studying the transition zone between two distinct substances in a composite material. It enables us to understand the chemical and physical interactions at the interfaces, which are crucial to the material's performance and stability.
- Corrosion, cracks, fractures, adhesion problems
By analysing the imperfections in your metal alloys, we can determine their origins and impact. We carry out detailed analyses of failures to provide an in-depth understanding of their nature and scope.
Checking the homogeneity of surface treatments is essential to ensure the uniform quality and performance of materials, making it possible to detect and correct any variations or defects in the treatment process. This verification guarantees the reliability and durability of materials in their specific applications.
Adhesion analysis is used to assess the strength with which two surfaces bond to each other, for example between a coating and a surface. Knowledge of this characteristic guarantees the reliability and durability of coatings and assemblies in the automotive, aerospace and electronics sectors, for example.
Shot peening is a surface treatment process in which small beads are impacted onto a material to improve its texture or mechanical properties. This laboratory process improves the fatigue, corrosion and wear resistance of metal components. This treatment is common in the aerospace and automotive industries.
During a laboratory roughness analysis, our experts measure the texture of a material's surface and quantify any irregularities. This surface analysis is used to verify specific performance and aesthetic criteria.
The delamination study is used to examine the layers of a composite material or with a coating in order to identify any signs of separation or anomalies. This information determines the structural integrity of composite materials used in aeronautics or construction, for example.
Laboratory tomography testing uses X-rays or other forms of radiography to create three-dimensional images of the inside of an object without destroying it. This method can be used to analyse defects in materials, helping to prevent failures in industries such as energy.

Surface characterization applications
Poor adhesion of a coating on a medical implant
In the medical device industry, problems with the adhesion of antibacterial coatings on titanium implants can lead to batches being rejected.
In such cases, the intervention of a laboratory specialising in surface characterisation is essential. Thanks to analyses such as XPS and SEM-EDX, it is possible to identify organic contamination that is invisible to the naked eye. This data can be used to adapt surface treatments and guarantee the conformity of medical devices.
Analysis and optimisation of thin films for luxury products
In the luxury goods industry, thin films are used to give products aesthetic and personalised finishes, such as gold or platinum coatings on jewellery. They also offer technical functions, such as scratch resistance for watches via layers of DLC or titanium nitride. To validate their performance, these films are analysed in the laboratory using techniques such as SEM, TEM or AFM. These tools are used to study their morphology, thickness and roughness. The chemical composition is determined using methods such as XPS or DRX.
