How we measure wear and friction
Our sliding wear apparatus can create different conditions: pin, line or area contact on either reciprocating or rotating plates. In every case, we can determine the wear rates and record friction measurements. We can also control many test parameters to simulate the real environment.
Wear rates can be assessed both by the mass loss of the pin and through 3D profilometry of any wear scars present in the plate. We record static and dynamic coefficients of friction during testing together with noise made by the sliding contact.
Ranking of materials
Our specialist engineers can use their experimental data to provide a ranking and also examine the worn surfaces. Using material characterisation techniques, we can interpret wear processes and give you an opinion on why the materials ranked the way they did.
