- Twist compression tester
The Twist Compression Tester ("TCT") is a
hydraulic ally operated bench-top apparatus used to evaluate the level offriction and/orwear between two materials under lubricated or non-lubricated conditions.Under controlled conditions, a rotating annular specimen is brought into contact with a non-rotating flat specimen. Specimens can be prepared from die materials, sheet or plate materials, metals or plastics.
The applied
normal force and thetorque are measured, and thecoefficient of friction is calculated.Although the twist-compression test does not simulate an actual process, it has been demonstrated to correlate well with processes where boundary lubrication predominates and lubricant depletion occurs.
The Twist Compression Tester is an invaluable diagnostic tool for: evaluating lubricants, materials and coatings; screening products for production; understanding the effect of additives in a lubricant; and many other value-added testing scenarios.
The Twist Compression Tester was developed by Professor John Schey formerly of the
University of Waterloo , and is manufactured, according to his design, under exclusive license by the Industrial Research + Development Institute (Midland,Ontario ,Canada ).
