With the use of the scanning electron microscopy it was determined that the obtained nanoparticles represent by themselves the nanospheres by diameter of 50 – 100 nm. The composition of obtained powders has been studied with the use of the XRD method. It was determined that the obtained nanoparticles don’t contain the copper and silver oxides. In accordance with the «ball-on-plate» method the tribological behavior of the friction pair «steel-steel» was studied in the medium of І–20А oil. It was determined, that the addition of 500 ppm of synthesized nanoparticles decreases the friction co-efficient in twice, and the friction track width on 25 %.
