Development and modification of Fe and FeCu nanoparticles and tribological analysis of the lubricants with nano-suspensions
Abstract
Purpose – The purpose of this paper is to investigate the possibility of using the iron nanoparticles and iron nanoparticles coated with copper layer as additives to base oils. Design/methodology/approach – Fe and Fe ž Cu nanoparticles were synthesized by a reduction modification method and added to mineral oil. The size and structure of prepared nanoparticles were characterized by SEM, TEM, XRF, AAS and XRD analysis. Tribological properties of modified lubricants were evaluated on a four-ball machine in a model of sliding friction pairs. Findings – Spectral and microscopy analysis evidently displayed the formation of Fe and Fe ž Cu nanoparticles in suspensions of colloidal solutions and oil. The size of formed nanoparticles was in 15-50 nm range. Tribological experiments show good lubricating properties of oils modified with Fe and Fe ž Cu nanoparticles: higher wear resistance (55 per cent and 46 per cent accordingly) and lower friction coefficient (30 per cent and 26 per cent accordingly). The tests show that nanoparticles provide decreasing tendency of friction torque during the operation of friction pair. Originality/value – The paper demonstrates that iron nanoparticles and iron nanoparticles coated with copper layer, not only reduce the wear and friction decrease of friction pairs, but possibly also can create layer in oil which separates two friction surfaces and have some self-organisation properties.
