The Method for Producing Copper Nanoparticles and Analysis of their Lubricating Ability

Abstract:

In this paper described the possibility for using the copper nanoparticles as additives to lubricating oil. Copper nanoparticle has a decreased melting point and low shearing strength, therefore, the particles exhibit a high degree of slip. Adding copper nanoparticles to lubricating oil, can reduce the friction and wear of the friction surfaces, increase engine power, while reducing air pollution with an increase operating life of the engine. In this paper also described the liquid reduction process as a method for copper nanoparticle manufacture, which can be carried out without expensive special equipment. Generally in the process of gathering products – nanoparticles need to use the ultracentrifuge, and there is the phenomenon of aggregation of nanoparticles. In this paper obtained copper nanoparticles with dimensions of 30-80 nm without using the ultracentrifuge by adding organic solvent to a solution of the reduction reaction. Also presented the test results for friction and wear of the parts in the environment of the lubricating oil added copper nanoparticles. The experimental test results confirmed the theoretical assumption that copper nanoparticles improve the operational properties of the oil and reduce the abrasion of the surface of friction parts.
