The subject of the invention is the method of the antifriction agent anufacture and the antifriction agent, made on a base of the particles of colloidal dispersion of copper or vanadium or chromium or cot alt or nickel or their oxides or their combinations. There are known additions to the lubricating media, mostly containing powders of tin(Su), copper(Cu), lead(Pb), zinc(Zn) or other metals, contents of which improves the characteristics which have an influence on the performance of plastic or liquid lubricants, thereby reducing friction and wear of co-acting parts and at the same time raising their electrical conductivity.

There are also known additions to fuels which have anti-smoke properties, decreasing the level of noxious substances in exhaust gases, especially in compression-ignition engines. Besides, there\'s known an addition to fuels which contains iron oxides thoroughly mixed with fuel. The optimum contents of iron oxides in fuel is 0.01 to 0.1 % of the fuel\'s weight, what allows to reduce the formation of soot by 21 . However, the anti-smoke properties of this addition are poor and there\'s a disadvantage of a lack of anti-slide properties, what limits its broad application.

From the Polish description of the invention ap; nation No. P-293400, there is a know- method of producing m addition, especially to the lubricating media, cutting flu and fuels on the base of particles of colloidal dispersion of copper or vanadium or chromium or cobalt or nickel or their oxides or their combinations, ace. to the invention where the method is, that to the necessary amount of the particles of the colloidial dispersion of copper or vanadium or chromium or cobalt or nickel or their oxides or their combinations - a liquid medium is added, at the best a low viscosity oil, so that per every two parts by weight of colloidal particles of pure metal there is one part by weight of the liquid medium. Then the ingredients are mixed. After that, a surface active agent is added, at the best oleic acid, so that per every two parts by weight of colloidal particles of pure metal there is one part by weight of the liquid medium and 0.8 to 1.5 parts by weight of surface active agent. Then the ingredients are mixed. Then the liquid medium is added to obtain such a proportion in which per two parts by weight of colloidal particles of pure metal there are two parts by weight of liquid medium and 0.8 to 1.5 parts by weight of surface active agent. The addition, especially to lubricating media, cutting tool lubricants and fuel, ace. to the Polish description of the application of invention No. P-293400 on the base of

particles of the colloidal dispersion of copper or vanadium or chromium or cobalt or nickel or their oxides or their combinations contains the percentage concentration of pure metal\'s atoms or ions in addition to the weight of lubricating media, cutting-tool lubricants or fuels from 1x10 ^"2 to 2.2x10 ~* . The purpose of the invention is the development of the method of manufacturing the antifriction agent and the antifriction agent itself, which increases the service life of co-acting parts. The method of the antifriction agent production on a basis of the particles of colloidal dispersion of copper or vanadium or chromium or cobalt or nickel or their oxides or their combinations, according to the invention, depends on that to the necessary quantity of the particles of colloidal dispersion of copper or vanadium or chromium or cobalt or nickel or their oxides or their combinations a liquid medium is added, at the best, low viscosity oil, so that per two parts by weight of colloidal particles of pure metal there\'s one to two parts by weight of liquid medium, mixing the ingredients at the same time. Then to the mixture a stabilizing surface active agent is added, at the best oleic acid, so after that, per two parts by weight of colloidal particles of pure metal there is one to two parts by weight of the liquid medium and 0.8 to 1.5 parts by weight of the surface active agent, mixing the ingredients. Then the liquid medium and aminobenzoic acid, at the best, are added until obtaining such a ratio where per two parts by weight of colloidal particles of pure metal we\'ve got 2.0 to 47 parts by weight of liquid medium, 0.8 to 1.5 parts by weight of surface active agent and 2.5x10 ^"2 to 5.0x 10 ^"2 parts by weight of aminobenzoic acid.

The antifriction agent on a bases of particles of the collodial dispersion of copper or vanadium or chromium or cobalt or nickel or their oxides or their combinations, according to the invention contains from 1x10 ^"2 to 2.2x0 ~* atoms or ions of pure metal, 0.5x10 ^"2 to 1.1x10 ~* of surface active agent , at the best - oleic acid, and 2.75x10 ^"6 to 2.5x10 of aminobenzoic acid - at the best, in relation to its weight. EXAMPLE

Prepare a solution of 34.5 g of sodium hydroxide in 600ml of water and filtrate it. Prepare a solution of 100g of blue vitriol in 400ml of water and filtrate it as well. Warmed up to the temp, of 70 ° C, the solution of blue vitriol is added to the solution of sodium hydroxide and the achieved mixture is mixed for 15 minutes and then poured into the water to get the volume from 2 1 to 4 I. The obtained mixture is subjected to the decantation until all the SO ₄ ions are separated, given, the separated water shouldn\'t become turbid in next 2 hours after adding barium chloride. Add the liquid medium to the obtained cupric oxide deposit, at the best, low viscosity oil, so that per two parts by weight of cupric oxide there is 1.5 parts by weight of the liquid medium. Mix the ingredients thoroughly, then add to the mixture the surface active agent at the best - oleic acid, to reach the proportion in which per two parts by weight of cupric oxide there is 1.5 parts by weight of the liquid medium and 0.9 parts by weight of surface active agent. Such a mixture is filled up with the liquid medium, not interrupting mixing, until its such contents is obtained where per two parts by weight of cupric oxide there is 20 parts by weight of the liquid medium and 0.9 parts by weight of surface active agent.

On obtaining the intimate mixture, the liquid medium is added, at the best- aminobenzoic acid, until a ratio is obtained where per two parts by weight of

cc.io.dε, particies of pure metal there is 2.0 ^" to 47 parts by weight of liqui rr.εcii .r, and 2.5x10 ^\'2 to 5.0x10 \' ² pirts by weight of aminobenzoic acid.

Obtained in this v- the mixture of the particles of colloidal dispersion of copper is added to lubricatir nedia, cutting fluids and fuels.
