To satisfy the growing demand for nanoparticles in the world market, manufacturers are increasing an extent of their production while researchers are developing modern methods of nanoparticles production or updating the existing ones. One of them is electrical wire explosion. This method was invented by Michael Faraday in 1857. He observed a thin layer of gold on the inner surface of glass jar by evaporating golden wire with pulse current. Now production of nanoparticles by electrical wire explosion is wide sprayed method which can be used to obtain various nanoparticles from any conductive material or their alloy. It is very effective method having high productivity and cost efficiency. The main electrical wire explosion parameters having influence on properties of nanoparticles are current value, voltage, diameter and length as well as material of wire. The properties of nanoparticles such as size, structure and size dispersion depend on energy and wire volume ration. Usually the current density is 1011 j 1012 A m2 , the wire diameter 0,25...0,5 mm and length 30…250 mm. The explosion can be made in any environment like inert (to obtain pure materials), or other environments (to obtain oxides, nitrides, carbides etc.). The various wire feeding methods are used to produce one or polimetallic nanopartecles [1, 2, 3]. The nanoparticles obtained by electrical wire explosion have average size of 14...50 nm [4]. They can be used in variety of industrial applications. One of them is their use as the additives in lubricating oils for improving their tribological properties and consequently increasing machine reliability [5]. A lot of efforts have been made to investigate an influence of nanoparticle concentration, material, size, and shape on tribological properties of different friction pairs and lubricating materials. In some cases using copper nanoparticles friction reduction of 40 % has been reached [5]. The sliding speed and loading conditions are important to get the best result with nanoparticles. Specific properties of nanoparticles should be chosen in particular applications [6, 7].
