3D ANALYSIS OF GEOMETRICAL SURFACE STRUCTURE IN TRIBOLOGICAL TESTS

摘要

The elementary friction phenomena occur on one momentary surface of actual contact, that is on the protrusions of irregularities. During operation, a new surface roughness state forms. For the measurement of parameters characterizing the geometrical structure of surface before and after the friction process, a profilometer by Taylor Hobson and the TalyMap Platinum 5.1.1 software were employed. The obtained full characteristics of the geometrical surface structure (GSS) in the 3D system and the program capabilities enable a more in-depth inference on the mating of tribological pair elements in a micro scale. The paper will present the possibilities of using 3D roughness measurements for the assessment of phenomena accompanying the friction and wear processes.
