Tribo-Rheometry

13-Tribo-Rheometry

Enables the capability to make coefficient of friction measurements between two solid surfaces under dry or lubricated conditions.

Tribo-Rheometry

Tribology is defined as the study of interacting surfaces undergoing relative motion. The new Tribo-Rheometry Accessory, available for all DHR models, enables the capability to make coefficient of friction measurements between two solid surfaces under dry or lubricated conditions. The unique self-aligning design ensures uniform solid-solid contact and axial force distribution under all conditions. A modular set of standard and novel geometries offers a choice of different contact profiles and direct simulation of end-use conditions. Accurate and precise control of axial force, rotational speed, and temperature inherent to TA Instrument rheometers provides for the best and widest range of friction measurements.

The advanced TRIOS software offers easy setup and control of tribo-rheometry tests and contains a complete set of variables required for data analysis including the coefficient of friction (μ), load force (FL ), friction force (FF ) and Gumbel number (Gu). These may be used to construct Stribeck curves, static friction measurements, or explore specific combinations of temperature, contact force, and motion.
