  Physico-chemical analyses: Thermal, chemical, spectroscopic analysis, etc.
  Physicochemical analyses enable the analysis of materials and their characteristicsin order to confirm their compositions or identify defects. Depending on the problems encountered, various analytical techniques can be implemented:
  • Metallic materials : SEM-EDX, ICP or SEO chemical analysis, GDMS, etc.
  • Organic materials : FTIR spectroscopy, Raman spectroscopy, DSC, GC / MC, etc.
  • Mineral materials : SEM-EDX, XRD, (...)

  CRYSTALLOGRAPHIC CHARACTERIZATION: From the identification of crystallographic forms to the quantitative determination of crystalline compounds
  Solids adopt naturally or not a crystallographic structure that can be used to determine certain characteristics in terms of formulation or performance. The properties (chemical, mechanical, etc.) of the materials are related to their crystallographic structure (s). X-ray diffraction is the essential technique for the crystallographic (...)

  STUDY OF CORROSION PHENOMENA: Searching for the cause of premature aging or the incompatibility between a material and its environment
  This type of defect can pose a risk to the reliability and strength of the materials. Understanding corrosion phenomena enables manufacturers to control the risks in relation to the relevant technical and economic issues.
  The capacity to implement the aging tests and analyze the corrosion phenomena involved is a specific feature of the Analyses & (...)

• MORPHOLOGICAL CHARACTERIZATION
  15 June 2015, by Administrateur

  Knowing the morphology and dimensioning of parts, surface layers, paints, or grains... is critical for controlling an industrial process. It is therefore important to know or control these parameters in order to validate the methods used in their production.
  • Microscopic observations of the morphology of powders or materials,
  • Macroscopic and microscopic surface and cross-sectional dimensional measurements,
  • Observation of the microstructure and Measurement of grain size,
  • (...)

  This equipment can quickly provide information on the morphology and elemental composition of a solid object. Its great ease of use, flexibility for viewing highly variable extension fields on massive samples, and the extent of its depth of field make SEM a vital tool in the exploration of the microscopic world.

  FRACTOGRAPHIC INVESTIGATION: Understanding and determining the origin of a failure
  The failure of a material, part or structure can lead to many economic consequences for an industrialist. When a failure occurs, it is important to identify its nature and origin in order to set up corrective actions.
  The laboratory’s skills in failure analysis allow us to carry out a full investigation using our high-performance test facilities. Our long-standing experience allows us to highlight (...)

• Visual defects

  THE ANALYSIS OF AN VISUAL DEFECT: Observing and determining the cause of the defect
  The appearance of a visual defect on a part is often evidence of a failure in the process. The defect can have several impacts on the product itself, from the aesthetics of the part to the impact on the very function of the part and can cause returns from customers. When this type of failure occurs, it is important to identify its nature in order to trace the origin of the problem.
  Our defect analysis will (...)

• FORENSIC EXAMINATION
  23 July 2018, by Thomas Lietart

  FORENSIC EXAMINATION : ACCOMPANYING EXPERTS IN DISPUTE RESOLUTION
  A part of forensic examinations and/or dispute resolution, an expert must call upon a service provider or specialist advisor laboratory to conductimpartial and technical investigations. In the ANALYSES & SURFACE laboratory, the expert finds the skills and the means with which to analyze all types of materials (metallic, mineral, organic), particularly in the fields of civil engineering, building/housing or industry. (...)

  THE RELIABILITY OF ELECTRONIC COMPONENTS: Determining the cause of a failure in an electronic component
  Finding a defect on a chip card and its components can be very long and difficult due to the size of the various existing electronic components. The occurrence of a fault even within a component can make its characterization difficult because of its size and the ability to disassemble it. Industrialists must be able to carry out the investigations required to solve the problem in order (...)

• Foreign Bodies & contaminants
  17 June 2015, by Administrateur

  The analysis of foreign matter enables identification :
  - Of the morphology of contamination,
  - Of the nature of the contamination,
  - Of the source of the contamination,
  Analyses et Surface has COFRAC testing accreditation (accreditation n°1-1720 - scope available on www.cofrac.fr) for the sampling and characterization of foreign bodies (particles, fibres) by Scanning Electron Microscopy coupled with X-ray microanalysis (SEM-EDX), stereoscopy and infrared microscopy (IRTF). (...)
