THE INFLUENCE OF ADDITIVES ON THE OXIDATIVE STABILITY AND FATIGUE LIFE OF LUBRICATED FRICTION PAIRS
Journal Title: Tribologia - Year 2019, Vol 284, Issue 2
Abstract
The objective of the study was to determine the influence of different additives, namely, graphite, nanostructures of carbon, and polymer PTFE on the lubricating properties in reference to grease based on paraffin oil without an additive. The synergies of different additives were examined when both were simultaneously added. The improvement of the friction properties may be caused by the chemical elements that are absorbed on the surface. The steel-steel friction contacts were lubricated with the use of the developed lubricants. The experiments were carried out with the use of a four-ball pitting tester. The relationships between additives and the tribological properties were analysed. The correlation between thermal stability of lubricants and fatigue life was evaluated.<br/><br/>
