MVT-2 Multi Function Vacuum Tribometer
Vacuum Tribometer Overview
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. Please contact us to discuss your application.
Vacuum Tribometer FeaturesThe 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
Cryogenic to high Temperature control
Close loop force control
|
Quick to reach vacuum
Rotary and Linear modes
Several Application Modules
|
Environmental Control
The friction coefficient and wear highly depend on environmental conditions. Therefore, tests should occur in conditions close to real application. MVT-2 has advanced close loop controllers to control temperature from -120°C to 400°C on same setup. Temperature can be changed automatically during the test.
