The Hysitron TriboIndenter, which can perform nanoindentation and nanoscratch testing, has the capability to perform in-situ scanning probe microscopy (SPM). The TriboIndenter’s piezo scanner can scan a probe tip across a sample surface up to 60 µm wide and at a maximum rate of 3 Hz. The setpoint applied during scanning is typically 1-2 µN. Analysis software, such as SIP or Hysitron’s TriboView, calculate surface roughness parameters from imported SPM images.
