Service offer CRAM06

- SEM - Scanning Electron Microscopy
Observations of materials in SE or BSE mode with nanometric resolution (up to x 1,000,000). Energy-Dispersive X-ray Spectroscopy (EDS) is available to perform distribution maps, determine the composition of materials or view distribution profiles of chemical elements. Variable pressure mode. Measurement of crystal orientations by Electron BackScatter Diffraction EBSD.

- Sample preparation:
To perform observations and analyzes in light microscopy and SEM. Carried out by sampling (cutting and micro-cutting), mechanical, mechanical-chemical, electrolytic and ionic polishing.

- DSC - Differential scanning calorimetry
Determines the phase transitions: glass transition (Tg), fusion, crystallization. Measurement of transformation enthalpies (endothermic or exothermic). Scanning speed from 0.10 ° C / min to 600 ° C / min depending on the equipment used. Sample temperature from -130 ° C to 450 ° C.
