Аннотация:Copper electrodeposited composite coatings containing two types of aluminum-oxide powders with different dispersities (alumina Al<sub>2</sub>O<sub>3</sub>-1 and electroexplosive aluminum-oxide nanopowder Al<sub>2</sub>O<sub>3</sub>-2) are obtained during the work. The studies show that introducing the powders leads to a change in the microstructure of the composites and a change in the grain growth principles during the formation of the coatings. Refinement and ordering of the grain structure of the coatings occurs and twinning defects and texture are formed. The change in the formation of the microstructure of the composites leads to a change in some operational characteristics: an increase in the microhardness (by 10% in the composites with the addition of alumina and by more than 30% in the coatings with electroexplosive aluminum oxide) and ultimate tensile strength (by 20% in the composites with Al<sub>2</sub>O<sub>3</sub>-1 and almost 1.5-fold in the samples with Al<sub>2</sub>O<sub>3</sub>-2).
