This study aimed at examining the tribological properties of nanolamellar molybdenum disulfide doped with copper nanoparticles. Nanolamellar molybdenum disulfide was produced using self-propagating high-temperature synthesis via the reaction between elementary sulfur and nanosized molybdenum powder prepared by electrical explosion of wires. Copper nanoparticles were also prepared by electrical explosion of copper wires. Comparative tribological tests were carried out for nanolamellar and commercial molybdenum disulfides doped with 7 wt.% of copper nanoparticles. It was demonstrated that doping copper nanoparticles additives reduce wear of the friction body when using both commercial and nanolamellar molybdenum disulfide.

Electrical Explosion Of Wires

Copper and molybdenum sulfide nanopowders were prepared by self-propagating high-temperature synthesis in argon. The initial copper powder and molybdenum powder were produced by electric spark dispersion in hexane and by electrical explosion of wires (EEW) in argon, respectively. The powders were studied by electron microscopy, X-ray diffraction and Raman spectroscopy. The copper sulfide main phase is hexagonal 2H-CuS, whereas hexagonal 2H-MoS2 and rhombohedral 3R-MoS2 are characteristic for molybdenum disulfide. The lattice parameters of copper and molybdenum sulfides were calculated. The average particle size of copper sulfide and molybdenum disulfide powders was about 50 nm and 80 nm, respectively.

The results of tribological characteristics of alumomatric composite material Al — 5 % Cu — 2 % Mn — 10 % TiC obtained by the self-propagating high-temperature synthesis method are presented. It is shown that in comparison with technical aluminum and matrix alloy, signifi cantly lower indicators of the coeffi cient of friction, wear and heating temperature characterize composite material, reinforced with nano- and ultrafi ne particles of titanium carbide.

Tribological properties of a composite mixture based on copper nanoparticles and nanolamellar tungsten disulfide powder have been studied. SEM of copper nanoparticles produced by electrical explosion of wires was analyzed. The tribological tests of pure tungsten disulfide and composite WS2-Cu lubricant are performed. Possible mechanism of copper influence to tribological properties of tungsten disulfide was discussed.
