Device data sheet in PDF format

In a tribotester, a flat, round or spherical counter-sample is pressed against the sample with a precisely known force. The counter-sample is mounted on a rigid element. The coefficient of friction is determined during the test by measuring the elastic deformation of the arm using appropriate strain gauges.

The linear wear coefficient of the sample and counter-sample is measured using a precision position (wear) sensor. This simple method allows the friction and wear of almost any known combination of materials in a solid state to be tested, with or without lubrication. 

"Control of test parameters such as speed, frequency, pressure, time, temperature, and humidity allows simulating typical real-life conditions for a given friction pair. An important feature of Elbit's tribotester is the ability to terminate the test upon reaching a predetermined time, distance, or wear depth."

"The tribotester can perform reciprocating motion, measuring the friction coefficient in both directions of displacement. This enables the study of changes over time in static and kinetic friction coefficients."

"As an additional option, tribotesters can be equipped with a housing that allows for the control of atmosphere with variable humidity and temperature. A special case is the ability to conduct tests in a vacuum."

"Another option is various interchangeable chambers:"

• "water (wet) chamber for tribological testing of elements submerged in lubricant, enabling tests at temperatures up to 150°C;"
• "high-temperature chamber for tests at temperatures up to 900°C."

"Of course, both chambers have systems for precise stabilization of the set temperature."

"The next option is an attachment for automatic testing of the electrical conductivity of the friction pair, which enables the examination of the insulating properties of coatings. The controlling software allows: - real-time calculation of the following values: force, load, distance, rotational speed, friction coefficient, temperature of the friction pair, temperature and humidity in the chamber, wear depth, electrical conductivity between the friction pair (option), friction coefficient, wear rate of both friction elements, stress; - adjustment (from the connected computer) of test parameters such as rotational speed, frequency, number of rotations, friction coefficient threshold, temperature, time; - easy archiving of measurement data and export to ASCII or Excel files; - Ethernet connection and presentation of basic test results during the test on a web page as well."

"The program window for reading measurement data looks as follows:"
