LUBRICATION STABILITY AND OXIDATION STABILITY OF MODIFIED GREASES
Journal Title: Tribologia - Year 2014, Vol 256, Issue 4
Abstract
This article presents the results of the oxidation stability and service life of greases prepared with and without the addition of modifiers. The effectiveness of the additives used in the grease was calculated based on the oxidative stability determined by thermal analysis methods. To test the ability of lubricants to provide protection through proper lubrication over a longer period of time, standard tests were carried out at a given load bearing, high speed, and elevated temperatures, allowing the determination of the service life of lubricants in conditions similar to real operating conditions. A positive effect of the additives on the oxidation stability and lubrication stability of greases was found.
