Vacuum Ball – Disk Friction Tester
Category：Abrasion Tester
Introduction
The Vacuum Ball – Disk Friction Tester （vacuum ball-on-disk friction tester） is a device used to simulate friction and wear behavior under actual operating conditions, in order to evaluate the performance of materials, lubricants, or other wear-resistant materials.
Application
The vacuum ball – disk friction tester is a device specifically used for evaluating the sliding friction coefficient of point contact and the wear life of materials under vacuum and different atmospheric environment conditions. Its main purposes include:
Material Friction Performance Evaluation
– Simulate the actual friction conditions of materials in a vacuum or specific atmospheric environment, test the friction coefficient of materials, and evaluate their friction performance. – Test the friction behavior of materials under different loads and speeds to obtain friction performance data, providing a basis for material research, development, and optimization.

FAQ
1. What is a Vacuum Ball-Disk Friction Tester?
This tester evaluates the friction and wear behavior of materials under vacuum conditions, simulating space or high-vacuum environments where lubrication and material performance may differ from normal atmospheric conditions.
2. How does the ball-disk friction test work?
A ball is pressed against a rotating disk under a controlled load inside a vacuum chamber. Friction force, wear, and sometimes temperature are measured to assess the tribological properties of the material pair.
3. What types of materials can be tested?
It can test metals, polymers, ceramics, composites, and coatings used in aerospace, vacuum equipment, and high-performance mechanical systems.
4. What parameters are measured during testing?
The tester measures coefficient of friction, wear rate, wear depth, friction torque, and surface damage. Advanced models provide automated data logging and in situ surface monitoring.
5. Why is vacuum ball-disk friction testing important?
Testing ensures materials and lubricants perform reliably in vacuum environments, preventing excessive wear, overheating, or failure in applications such as spacecraft mechanisms, satellites, and high-vacuum machinery.
