Vacuum Friction and Wear Tester
The Vacuum Friction and Wear Tester integrates a proven friction and wear testing mechanism into a sealed vacuum chamber, enabling reliable tribological testing under controlled vacuum conditions. By reproducing low-pressure environments that are difficult to simulate with conventional equipment, this system makes friction and wear evaluation under vacuum straightforward and repeatable. It is especially suited for performance assessment of materials, coatings, and components used in aerospace, advanced materials research, and emerging technologies where ambient-pressure testing is insufficient.
Application
This tester is designed for friction and wear evaluation in vacuum or reduced-pressure environments, covering a wide range of materials and surface treatments.
Typical applications include:
Tribological performance testing of aerospace structural materials under vacuum
Evaluation of solid lubricants and dry-film coatings in space-simulated environments
Friction and wear assessment of ceramics, precision metals, and surface-engineered materials
Research on new materials and technologies requiring environmental control
Comparative testing of coatings, polymers, and composites under vacuum conditions
Applicable test specimens include metal samples, ceramic components, coated substrates, polymer materials, and functional surface layers.
