• 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,
  • (...)

  CHARACTERIZATION OF COATING STRENGTH: The characterization of surface coatings
  The Analyses & Surface CRT is equipped with standardized hardware and has developed the skills to meet the increasingly stringent technical and regulatory requirements (higher temperatures, more aggressive environments, vibration, high stress, high pressures, REACH recommendations or standards, etc.). These parameters require evaluation and the qualification of coatings and their refractory life according to (...)

  Nanometric Non-contact surface topography measurements Principle
  Optosurf interferometric measurement system is based on Michelson’s interferometer principle (interferences between a reference mirror and the sample’s surface).
  The sample is lighted up by a filtered white light source. 50% of the beam is sent on a reference surface (mirror) thanks to a separative slide. The other part lights up the sample’s surface. Reflected beams from the mirror and the sample are combined on the (...)

  GLASS FAILURE ANALYSIS : Investigation, Analysis and Failure Analysis
  Glass is a material apart, discovered thousands of years ago. Our knowledge about it, as well as the capacity to analyze it and carry out a failure analysis are more recent. Like every material, it is important to know the characteristics of glass materials and enamels as part of assembly control, of both the container and content as well as in cases of defects or failures.
  The Analyses & Surface laboratory (...)

  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 (...)

• ADDITIVE MANUFACTURING

  ADDITIVE MANUFACTURING : In order to validate the production characteristics of parts from metal additive manufacturing, it is necessary to control the complete manufacturing process, from modeling to qualification, with non-destructive methodologies.
  The production of high value-added parts by metal additive manufacturing processes is a rapidly growing sector. The technology enables the production of parts that are highly complex to make using conventional machining (by removal of (...)
