Scanning Electron Microscope Lab

1. Lab Description and Capabilities

  • Characterize surfaces properties and composition at high resolution
  • Characterizing the mechanism of corrosion through high resolution images of the surface of materials. In addition, scientists and engineers would like to have information on the elemental composition of oxide films and corrosion products, grain orientation, oxide thickness and subsurface characteristics

2. Deliverables

  • High resolution imaging services to the corrosion engineering scientific community
  • Elemental composition analysis:
    • Oxide films and corrosion products
    • Grain orientation
    • Oxide thickness and subsurface characteristics

3. Major Equipment and Specific Minor Equipment

  • TESCAN LYRA‐3 Model XMU Integrated Variable Pressure FIB‐FESEM
  • Computer‐Controlled Focused Ion Beam – Variable Pressure Schottky Field Emission
  • TESCAN 3D Tomography Basic ‐ Software Module for serial / 3D SEM Imaging of FIB prepared sections: Automated data acquisition wizard with user‐customizable FIB presets, sample volume definition, and process parameters
  • TESCAN AutoSlicer – Automated preparation of multiple TEM lamellae (prior to lift‐out) and/or multiple cross sections. Structures can be milled at several stage locations or it is possible to define a mesh of structures
