Vacuum Ball - Disk Friction Tester

Main Purposes of Vacuum Ball - Disk Friction Tester

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.

Wear Life Testing

- 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.

Environmental Simulation Testing

- 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.

Applicable Standards

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):

General Friction Testing Standards

Such as the general friction test methods and specifications formulated by ASTM (American Society for Testing and Materials) or ISO (International Organization for Standardization).

Material Performance Testing Standards

Performance testing standards for specific material types, such as metallic materials, polymer materials, ceramic materials, etc.

Vacuum Environment Testing Standards

Such as standards and specifications regarding vacuum degree control and atmospheric environment simulation.
