Influence of Nanoadditives on Lubricants Tribological Properties
Keywords:molybdenum nanoparticle, lubricant, tribological properties, nanostructure, nanopowder
The paper deals with the influence of base oils (applied for lubricating and cutting fluids compounding) modification with metal micro- or nanoparticles addition on tribological properties of friction couples. The results of tribological investigations are presented as well as amount of wear measurements, and friction surface structure and composition examination results. Molybdenum nanoparticles added to some base oils modify their tribological properties observed in model sliding friction couples made in this purpose of materials characteristic for machining systems (steel C45 cooperating with sintered carbide S20S). Such field of investigations results from only few reports of some authors about positive influence of metal nanoparticles applied as additives to lubricating oils and mainly from the examination made by the author in this research area. Examination results presented in the paper prove positive influence of molybdenum nanoparticles addition on tribological properties of lubricants consisting in wear decrease in couples lubricated with these lubricants.
