Vacuum Tribometer MVT-2
Vacuum Tribometer MVT-2
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. Runs 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 indentation, scratch and tribology tests on the same platform. The vacuum chamber comes in various standard configurations.
Rtec Instruments develops and manufactures advanced mechanical and surface testing and measurement solutions for research and industrial applications. They specialise in combining techniques that provide a unique perspective in material testing. Their testers include tribometer, profilometer, scratch tester, high-temperature indenter, and corrosion testers. Furthermore, their testers provide the most robust and versatile platform in the market for testing friction, wear, adhesion, hardness, roughness, and film thickness from nano to macro-scale.
- 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.

H: Data Acquisition, Motion Controller - Advanced high speed, low noise, fast feedback, high data acquisition rate controllers
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.
