High Vacuum Friction and Wear Tester
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.
Application
Friction and wear performance testing of metal materials, ceramic materials, and composite materials in high-vacuum environments;
Tribological performance evaluation of functional coatings, solid lubricant coatings, and surface-modified layers under vacuum conditions;
Material selection research for aerospace structural components, space motion mechanisms, and vacuum transmission components;
Performance verification of components operating under vacuum or low-pressure conditions in precision machinery and the automotive industry;
Research on vacuum friction and wear mechanisms conducted by research institutes, university laboratories, and material testing organizations.
