Friction tester is an equipment commonly used to test frictional features of various materials in dry or lubricated interacting motion contact. Friction testers can be used to test a wide range of materials including metals, composites, ceramics, polymers, fluid lubricants, greases, cutting fluids, coatings, etc.

Salient Features

• Available in various configurations like ball on flat, pin on flat and cylinder on flat contact area.
• There is arrangement for electronic control of temperature, frequency and stroke length.
• The equipment requires small specimen size or sample for testing.
• Custom configurations are available for the equipment.
• Provided with necessary software for record and graph test results.

Working of Friction Tester

• Friction test is conducted by loading the specimen to be tested against a ball, pin, or cylinder undergoing interactive linear motion.
• There is a force transducer to measure the frictional force developed at the contact interface.
• There is a storage oscilloscope that records the output signal.
• A unique velocity profile is created by the reciprocating motion of the ball. This allows to monitor static and dynamic frictional force over a wide range of linear sliding speeds.
• Wear testing can be performed on the test specimen by evaluating the resulting wear scar with a profilometer.

Application

Some of the applications of friction tester are:

• Aerospace
• Defense
• Airport Runways
• Analytical & Test Instruments
• Industrial Products & Materials
• Heavy Vehicles & Mass Transit
• Motors/Air Moving n Semiconductors
