Auger Lab

1. Lab Description and Capabilities

  • PHI 710 Scanning Auger Nanoprobe

2. Deliverables

  • Surface analysis of metal, metal oxide, and coating-metal interfaces
  • Imaging analysis of how corrosion proceeds from a pinhole or a scratch
  • Chemical mapping of wear in alloys, multilayers, and in tribological applications
  • Analysis of chemical bonding between organic and metal surfaces
  • High resolution chemical mapping of metal and metal oxide surfaces (8 nm spatial resolution)
  • Chemical mapping as a function of depth (5-100 nm)
  • SEM imaging that provides topographical and chemical information

3. Major Equipment and Specific Minor Equipment

  • UHV test chamber with ports to accommodate FIB, EDS, EBSD, and EBS
  • Schottky field emission electron gun with high spatial resolution and large energy range (1-25keV)
  • High sensitivity, high contrast scintillation detector for secondary electron imaging
  • 5 kV floating column argon ion for surface cleaning, charge neutralization, and Auger compositional depth profiling and high or low impact energies
  • Sample parking and high impact fracture with storage for up to 6 specimen in vacuum
  • Digital camera capturing optical images of the sample holder in the introduction chamber
  • Fully motorized, computer driven five axis precision specimen stage for rapid, accurate, and easy positioning
  • 60 mm specimen introduction and magnetically coupled transfer system
