Tribometer Vacuum

Vacuum Tribometer (VTHT / VTRB)

The Vacuum Tribometer is used to determine the sliding life of self-lubricant coatings as well as the friction and wear behaviour of solid-state materials or hard coatings with averaging time, contact pressure, velocity and temperature under vacuum conditions.
Anton Paar Tribometers have proven their reliability worldwide in over 1000 laboratories, for studying:

  • High vacuum environment down to 10e -7 mbar  
  • New materials (ceramics, metals, polymers)
  • Self-lubricating systems
  • Quality assurance
