The methods of metallography, scanning electron microscopy, microscopic x-ray spectral analysis, x-ray diffraction analysis, atomic force microscopy, x-ray photoelectron spectroscopy, Auger spectroscopy, scanning profilometry, and measurement of microhardness are used to study the structure of the surface of specimens of "steel - steel" tribotechnical mating parts operating in lubricants alloyed with nanopowders of copper, zinc, and brass. The friction factors and wear are determined for the lubricants. The strained state of the surface layers formed under friction in media with nanopowders is considered.
