Vacuum Ball - Disk Friction Tester
Vacuum Ball - Disk Friction Tester is a precision tribological testing instrument designed to evaluate friction coefficient, wear behavior, and service life of materials under vacuum or controlled atmospheric environments. The tester uses a ball-on-disk contact method to simulate real friction conditions between materials, while controlling parameters such as load, speed, and environmental atmosphere. It is widely used for studying the friction and wear characteristics of metals, ceramics, polymers, coatings, and solid lubricating films in special application environments such as aerospace, vacuum equipment, and advanced material research.
