Cryogenic Tribometer

The  wear resistance of a samples can be evaluated by Cryo-Tribometer  using pin-on-disk Module. An image processing system complete with camera mounted on an optical microscope, equipped with analysis of traces of wear, measurement of dimensions and to obtain information on the interaction between Pin and sample. The profilometer  allows you measure the width and depth of the tracks, as well as the average height of the peaks measured on the bottom. Once these measurements have been made, it is possible to obtain the volume of material removed from the surface of the sample. The test can be performed in DRY mode, i.e. without using any cooling or lubrication means in the contact area between the Pin and the sample, this obviously involves heating between the two parts in contact, or cryogenic mode, i.e. using liquid nitrogen flux
