Maintenance of any mechanical system is essential to prevent and mitigate failures. However, ongoing operation and maintenance, and unscheduled maintenance across industrial applications are costly with bearings and gearboxes contributing significantly to downtime and cost of repairs. This abstract presents a technology of nano- and microparticle-based phyllosilicate-additive for lubricants. It is proven that the phyllosilicate additives can improve and repair existing wear damage and protect the mechanical systems. The technology involves an innovative lubricant additive with a protective and repairing effect, which mainly consists of phyllosilicates in the form of micro- and nanoparticles. The particles take advantage of lubricant as a carrier to reach the rubbing contacts and repair/protect the damaged surfaces. This results in significantly greater reliability and a longer lifetime of the mechanical system. In this study, 2-disc tribometer was used to simulate the tribological system in gears and precisely monitor the friction and temperature at the surface during the experiments. In addition, the wear and roughness measurements were carried out using 3D-profilometery before and after each test. The results indicated that the nano- and microparticle-based phyllosilicate-additive can mitigate the wear damage and reduce friction and surface roughness. The particles are added to the lubricant after 20 h of running and the test was carried out with the phyllosilicate particles for another 20 h. The temperature at the surface of the disc was monitored during the test. The data proved that the temperature of the surface reduced after adding the nano- and microparticles to the lubricant which can significantly boost the efficiency of the tribological system. A series of tests which highlight the impact of the phyllosilicate-additive on repairing the existing damage and extending the lifetime of the tribological system by reducing friction, temperature and surface roughness will be presented in this presentation.
