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
