Vacuum Ball - Disk Friction Tester

A 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.

Test Procedures

- Calculate the wear life of materials by measuring the friction and wear conditions when the ball specimen rotates on the disk specimen. - Evaluate the performance changes of materials during long - term friction and wear processes, providing support for the assessment of material reliability and durability.

- Friction tests can be carried out in a vacuum environment to simulate the friction behavior in special application scenarios such as space and the nuclear industry.

- By adjusting the atmospheric environment, such as argon, nitrogen, etc., study the influence of different atmospheres on the friction performance of materials.

Lubricating Film Performance Evaluation

- For lubricating film materials, their wear life can be evaluated by testing the number of rotations before lubrication failure.

- Study the friction performance of lubricating films under different conditions to provide support for the research, development, and optimization of lubricants.

When the vacuum ball - disk friction tester conducts tests, it may need to comply with the following relevant standards or specifications (the specific standards may vary depending on the instrument model and application field):

Material Performance Testing Standards
