Abstract

The article presents the results of a study of microhardness and wear resistance of electroplated coatings based on zinc, with the inclusion of Al2O3 nanosized particles in the composition. It has been established that when nano-sized powders are introduced into galvanizing electrolytes, there is a change in microhardness and wear resistance. Thus, when adding from 1 to 9 g/l of Al2O3 nanosized materials to the electrolyte, the microhardness of the resulting coating increased by 10–65%. The best results were obtained for the coating modified with nanosized particles with a concentration of 5 g/l - 657 HV units. Wear resistance tests showed that the total wear of specimens coated with nanocomposite galvanized zinc is 1.5–1.7 times less than that of specimens coated without adding nanosized aluminum oxide particles to the electrolyte.
