Vacuum Tribometer
Vacuum Friction and Wear Tester is a specialized tribological testing system designed to study friction, wear, and related surface interactions under vacuum conditions. By precisely controlling normal load, sliding speed, and temperature, the system enables detailed analysis of material behavior in high vacuum or inert gas environments. Its unique mechanical design and high-precision force sensors ensure excellent data accuracy and repeatability. Multiple tests—including friction, wear, lubrication, scratch, and hardness—can be performed on a single platform, making it suitable for advanced vacuum tribology research and material evaluation under extreme conditions.
Application
The Vacuum Friction and Wear Tester is used for investigating tribological behavior under controlled vacuum or inert gas environments, including:
Friction and wear evaluation of materials under high vacuum, high-temperature, and low-temperature conditions
Study of surface friction, wear, and adhesion mechanisms unique to vacuum environments
Tribological testing of coatings, bulk materials, and surface-modified components
Vacuum lubrication performance evaluation for materials and lubricated surfaces
Scratch, indentation, and hardness testing under vacuum conditions
Typical test configurations include rotational friction, linear reciprocating friction and wear, indentation, and scratch testing, all conducted on the same testing platform.
Standards
The tester is designed to support test methods referenced in the following standards:
ASTM G99 (Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus)
ISO 20808 (Fine ceramics — Determination of friction and wear characteristics of monolithic ceramics by ball-on-disk method)
GB/T 3142 (Determination of load-carrying capacity of lubricants — Four-ball method)
SH/T 0189 (Test method for anti-wear properties of lubricating oils — Four-ball method)
ASTM D3702-24 (Standard Test Method for Wear Rate and Coefficient of Friction of Materials in Self-Lubricated Contact)
ISO 1461:2022 (Hot dip galvanized coatings on fabricated iron and steel articles — Specifications and test methods)
