Pin on Disc type Tribometer Friction & Wear Machine
The Tribotech Tribometer uses a pin-on-disk system to measure wear. The unit consists of a gimbaled arm to which the pin is attached, a fixture which accommodates disks up to 165 mm in diameter & 8 mm thick, an electronic force sensor for measuring the friction force, and a computer software (on Labview platform) for displaying the parameters, printing, or storing data for analysis. The motor driven turntable produces up to 3000 rpm. Wear is quantified by measuring the wear groove with a profilometer (to be ordered saperately) and measuring the amount of material removed. Users simply specify the turntable speed, the load, and any other desired test variables such as friction limit and number of rotations.
Designed for unattended use, a user need only place the test material into turntable fixture and specify the test variables. A pre-determined Hertzian pressure is automatically applied to the pin using a system of weights. Rotating the turntable while applying this force to the pin includes sliding wear as well as a friction force. Since pins can be fabricated from a wide range of materials virtually any combination of metal, glass, plastic, composite, or ceramic substrates can be tested.
Software included with this model provides for quick calculation of the Hertzian pressure between the pin and disk. The cup-like (housing) enclosed fixture permits the use of liquid lubricants during a wear test (optionally)

The friction coefficient signal is displayed in real time on a PC Screen. Data can be viewed as it is logged for the entire specified test duration, which can be recalled later for detailed analysis. The software allows 9 different logged test files for on-line analysis / mapping The software displays the test time, turn count, linear velocity, and user-defined test parameters. This data can be stored and printed along with the friction traces.
Records friction and wear in sliding contact in dry, lubricated, controlled environment and partial vacuum.
Fundamental wear studies. Wear map ping and PV diagrams. Friction and wear testing of metals, ceramics, soft and hard coatings, plastics, polymers and composites, lubricants, cutting fluids, heat processed samples.
Instrumentation and Data Acquistion System for the measurement of
PC acquires data online and displays it in several ways. Graphs of individual tests can be printed. Results of different tests can be superimposed for comparative viewing. Data can be exported to other software.
