Аннотация:In this work, nanomaterials based on FeIIICoII and FeIIINiII mixedoxides were obtained for the first time by thermal decomposition of polymer complexes of Fe and Co or Ni nitrates withacrylamide. During thermolysis, core-shell nanomaterials areformed containing nanoparticles of FeCo and FeNi oxidesuniformly distributed inside the carbon layer. These nanomaterials are characterized by high chemical and thermalstability. During thermolysis, nanoparticles of mixed oxidesFeCo and FeNi were formed with an average crystallite size of13–22 and 22–33 nm, respectively. Nanomaterials were testedas antifriction and antiwear additives to liquid industrial oil I-20 A. The values of the friction coefficient decrease by morethan 60% when CoO.Fe2O3 with a concentration of 0.05% isadded to the industrial oil I-20 A.
