%X Silver-copper core-shell nanoparticles containing of 1 % per mass of the silver have been synthesized in accordance with the two-stage scheme. With the use of the scanning electron microscopy it was determined that the obtained nanoparticles represent by themselves the nanospheres by diameter of 50 ¨C 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  ¨C20§¡ oil. It was determined, that the addition of 500 ppm of synthesized nanoparticles decreases the friction coefficient in twice, and the friction track width on 25 %.
