A promising direction of creation of new lubricants is their modification by nanoclusters of metals, which form in the zone of friction of the protective film, providing reduction of wear of friction pairs. In this regard, the aim of this work is to study tribological properties of lubricating compositions containing nanosized particles of lead and palladium. A lubricating composition was obtained in aqueous solution during electrolysis with a lead anode or in the presence of salts of palladium in an ultrasonic field (complex processing). Tribological studies showed that the lubricating compositions have high anti-wear and extreme pressure properties.

Currently widely advertised and offered on the domestic and global markets: anti-wear additives to motor, gear, industrial oils. Developed a method of producing nanoclusters of copper, lead and palladium in water-alcohol environments and the possibility of realization of the effect of wearless friction when using such a lubricating composition to the rubbing steel surfaces. The studied tribological properties of metal nanoclusters in aqueous solutions of multinuclear alcohols with the use of mechanical friction machine AE-5.

Developed 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.
