Abstract
Production of nano-particles of metals and their effect on tribological characteristics of lubricant сompositions
Incoming article date: 05.02.2016Developed a method of producing nanoclusters of copper and lead in water -organic solution with a soluble anode with simultaneous dispersion in the friction layer of metal recovered at the cathode. The topographic studies of the nanocluster metal structures are performed with the scanning probe microscope (SPM) Solver P47H. Tribological properties of steel-steel friction pair are studied on the front friction machine AE-5. In the result, the following is established. It is shown that in the process triboelectrochemical process the nanoclusters are formed of copper and lead with a height of about 100 nm. The possibility of realization of the effect of wearless friction when using a lubricating composition containing nanoscale particles of copper and lead to rubbing steel surfaces. On the friction surfaces is formed servovite film, which improves frictional characteristics of the contact and reduces wear of the contacting surfaces.
