DETERMINATION OF MECHANISMS OF WEAR FOR ROLLING- -SLIDING CONTACT IN SELECTED OPERATIONAL CONDITIONS BY MEANS OF SURFACE TOPOGRAPHY AND MES STUDIES
Journal Title: Tribologia - Year 2017, Vol 273, Issue 3
Abstract
The paper presents the influence of selected operating factors, i.e. load, slip, and wear rate, and surface conditions. The wear mechanism between the cooperating rolling surfaces in the rolling/sliding combination varies due to the interaction of the complex stresses / deformations caused by the variable operating conditions. Surface roughness studies have allowed determining the stereological parameters that are specific to the set type of wear. In addition, simulation studies using the Finite Element Method in a roll-to-roll system have been used to determine the value and depth of maximum stresses and deformations occurring in the surface layer due to the interaction of two co-operating bodies. Geometric models have the same properties and disadvantages as the surface layer in a real object. Reflecting the operating conditions and defining the wear mechanisms in the proposed research allowed us to determine the state of the surface layer and predict its durability.
