Home > Tribometers > Vacuum Tribometer


Main Features:

  • 10-7 Torr vacuum
  • mN to 200 N friction and down force
  • Cryogenic cooling from -150°C
  • Interchangeable tribology, hardness and scratch modules
  • Up to 400°C (1000°C) temperature range

Why Vacuum tribology – Advancement in space, semiconductor, aerospace, and thin films have resulted in several studies focused on material and coating properties under vacuum. Friction, wear, and adhesion of surfaces under vacuum are very different compared to ambient conditions. To develop next generation vacuum compatible components, and materials it is necessary to test them under conditions close to real applications.

Rtec Vacuum Tribometer MVT-2 comes with a wide force, speed, and test temperature range for analysis of materials properties under vacuum conditions. Unique design with patented force sensors, creates data with high accuracy and repeatability. The open face design provides a complete view of the chamber while changing samples.  Run several common friction lubrication and wear tests, such as pin-on-disc, ball-on-disc, and linear reciprocating tests on the same platform. The unique  design allows to run indentation, scratch and tribology tests on same platform. The vacuum chamber comes in various standard configurations.

The vacuum tribometer has several key design features that makes it the only commercial available tribometer to run a wide test conditions on same platform.
Patented force sensor

Capacitive sensors work across a high vacuum range with no drifts or degassing. 

Cryogenic to high Temperature control

Close loop temperature controller. Up to -150°C nitrogen cryogenic cooling chamber. Standard 400°C or high power 1000°C heating chamber.

Close loop force control

Real-time  close loop force control during the test.  This allows to create automatic friction vs load and speed curves.

Quick to reach vacuum

Reach 10-7 torr vacuum in 45 minutes. Vacuum tribometer has integrated rough and turbo molecular pumps

Rotary and Linear modes

Rotary speed up to 5000 RPM, Linear speed up to 6 mm/s. Additional  Piezo drives for precise motions.

Several Application Modules

Configeration allows to do scratch, indentation and tribology test on same platform.

Environmental Control
