K93400 Friction Tester Evaluates the dynamic friction at reciprocatory contacts of dry or lubricated materials as the function of normal load, velocity, frequency, temperature, and time. A wide variety of materials including fluid lubricants, greases, cutting fluids, metals, composites, ceramics, polymers, and coatings can be tested. The test is conducted by pressing the test specimen against a ball, pin, or cylinder undergoing reciprocating linear motion, producing a sinusoidal velocity profile which allows for the monitoring of static and dynamic friction force over a wide range of linear sliding speeds. The test load, stroke, frequency, and temperature can be adjusted to simulate different conditions. The frictional force developed at the contact interface is measured by a piezoelectric force transducer equipped with a charge amplifier. The test results can be displayed and recorded on a storage oscilloscope or acquired on a PC with the TriboDATA acquisition software for evaluation. Wear analysis of the sample can also be evaluated with a profilometer.
