MEASUREMENT OF WEAR RATE
This is data as important as measuring the coefficient of friction during a test or a tribological study.
Our profilometer measures the worn surface of the furrow with great precision (resolution: 7.55 manometer in Z) without dismantling the sample, which allows the test to continue in the same furrow, in the event of insufficient wear.
This profilometer is equipped with a probe without pad, with
internal reference which allows:
- to carry out measurements on samples with a minimum dimension of 2 mm,
- to carry out reliable measurements with the greatest precision of wear track.
Our software allows automatic measurement of the worn surface to instantly obtain the calculation of the wear rate in the Tribotester software and on the test report .
It's common knowledge that humidity provokes rust, which leads to destruction of metals, process accelerated by applying friction.
Due to it's lengthy process it was impossible to study this phenomenon, until recently. Electric current applied on a sample submerged in a corrosive liquid allows us to obtain, in a few hours, corrosion that takes month or years to obtain naturally. In this manner, tribo corrosion has been studied by installing a polymer cell on a tribometer, containing
the sample to be tested in a corrosive liquid, connected to a potentiostat that applies an electric current in different ways.
The innovation of Tribo corrosion technique permits us to study the phenomenon of friction and corrosion in a reduced and accelerated time frame.
Our Potentiostat/Galvanostat is linked with TRIBOtester software able to handle electrochemical parameters (current and/or potential) are continuously recorded in parallel to friction force and coefficient friction curves . Our software automatically calculates chemical wear.
This innovative system saves you time and relieves you of all the tedious tasks.
HIGH TEMPERATURE FRICTION TESTS
For your high temperature tribological needs we propose a new 600°C heating module for our TRIBOtester.
High temperature tribology is considered to begin from a minimum temperature of 300 - 350 °C, where organic base oils and polymers begin to decompose. In this field of tribology, tests are typically run under dry or solid-state friction, unless a solid lubricant is used, since
most lubricants will oxidize or break down when exposed to these extreme temperatures.
Therefore, this form of tribotesting is useful to determine the friction, wear, and other tribological characteristics of coatings, ceramics, cermets, alloys, and similar materials.
The test can run under a wide range of motion, load, and speed and permit to study material and coating friction coefficient and wear rate.
The dominant wear mechanisms are adhesive material transfer and abrasive material removal.
CONTACT RESISTANCE MEASUREMENT :
Measurement of electrical resistance with specific software capable of managing the measurement of electrical resistance recorded and continuously mixed alongside the friction force and friction coefficient curves.
