The High Frequency Friction Machine is a reciprocating tribological testing instrument designed to study high-frequency friction, wear, and tribological behavior of metals, ceramics, and composite materials under dry or lubricated conditions. You can apply controlled loads up to 1,000 N over a maximum stroke of 25 mm while precisely controlling frequency, temperature, and test sequence via PC interface and dedicated software. The system has been validated through multi-laboratory comparisons during ASTM G133 and ASTM G181 standard development, ensuring high reliability and international recognition.
Application
You can use this instrument for:
(1) Investigating dry and lubricated wear of metals, ceramics, and ceramic-based composites.
(2) Linear reciprocating ball-on-flat friction and wear tests.
(3) Evaluating friction performance of piston rings and cylinder liner materials under lubrication.
(4) Studying friction and wear of surface-engineered materials, including coatings and treated layers.
(5) Friction noise and stability analysis under reciprocating contact.
(6) Low-speed sliding and stick-slip behavior studies.
(7) Investigation of friction potential, contact states, and lubricating film formation.
(8) Simulation of gear, cam-follower, and rolling-sliding composite contact mechanisms.
(9) Fretting wear and impact fretting wear testing.
(10) Tribological testing under inert, low-temperature, or corrosive environments.
Standards
You can perform tests in accordance with:
(1) ASTM G133 – Linear Reciprocating Ball-on-Flat Sliding Wear Test
(2) ASTM G181 – Friction Test Method for Piston Rings and Cylinder Liner Materials
(3) ASTM D5706 / D5707 / D6079 – Lubrication and friction-related testing
(4) ASTM G203 / G206 – Friction, wear, and surface failure testing
(5) ISO/DIS 12156-2 – Lubricity evaluation (HFRR related)
(6) BS EN 1071-12 – Advanced ceramics friction and wear testing
(7) CEC F-06-A-96 – Diesel fuel lubricity evaluation
(8) DEF STAN 91-110/1 – Fuel lubrication performance assessment
