Linear Constant-Speed Reciprocating Friction and Wear Tester
The Linear Constant-Speed Reciprocating Friction and Wear Tester is a specialized instrument for evaluating friction and wear performance of materials and surface coatings under linear constant-speed sliding conditions. The instrument can accurately measure friction coefficient, wear depth, wear width, and wear volume under various loads, sliding speeds, stroke lengths, and temperature conditions, in dry or lubricated environments. The testing process is computer-controlled with real-time data acquisition and graphical display, suitable for material research, process evaluation, and quality control.
Application
Friction and wear testing of metallic materials.
Wear resistance evaluation of non-metallic materials (plastics, rubber, composites).
Tribological study of surface coatings, platings, and surface-modified layers.
Testing of solid and liquid lubricants’ friction performance.
Analysis of material surface processing effects on friction and wear behavior.
Material failure mechanism and reliability research.
Industrial product quality inspection and process control.
