Thin Film Characterization

Graph A
Real time coefficient of friction measurement of ultra low friction thin film. Environment: salt spray; Distance traveled: 2400 meters
Graph A
Wear measurement of same film as above. Vertical scale is 1 micron
Graph A
XRD of super corrosion inhibiting film developed by WSCG
Some film characterization methods:
  • Electrochemical Impedance Spectroscopy for corrosion rate measurements.
  • X-Ray Diffraction Spectroscopy
  • Coefficient of friction (5 methods)
  • Wear rate
