摘要

Abstract—

By thermal decomposition of nickel carboxylate and zinc carboxylate based on substituted aromatic acids, nickel oxide and zinc oxide nanoparticles were obtained, respectively. It was shown that the shape of nickel oxide nanoparticles is spherical with a particle size of up to 55 nm and the shape of zinc oxide nanoparticles is close to pyramidal with sizes of up to 60 nm. It was proven that the introduction of nickel oxide nanoparticles with a concentration of 0.05% into industrial oil as an additive increases the antiwear properties of the friction surface by 25% and zinc oxide nanoparticles with a concentration of 0.025% increases the antiwear properties of the friction surface by 20%.
