The High Vacuum Friction and Wear Tester is designed and manufactured in strict accordance with GJB 3032. It is used to simulate the friction and wear behavior of materials and their surface coatings under high-vacuum environmental conditions. Under controlled vacuum conditions, the equipment can accurately measure friction force, coefficient of friction, and wear characteristics of materials in rotary or reciprocating friction states, providing reliable experimental means for the study of tribological properties of materials under vacuum operating conditions.
