In our research, we have focused on the estimation of tribological and mechanical characteristics of self-organized copper film, formed through a friction of brass-steel pair in aqueous solutions of carbolic acid. We have found out that self-organized copper film formed through a friction interaction of pair brass-steel is nanostructural. The data obtained through the indentation of self-organized copper films indicated size effect. With an increasing load and contact area of interacting bodies, the coefficient of friction first drops sharply with an increasing normal load and then begins to grow. We have found out that the adhesion component of friction contributes to the friction coefficient at small loads. We have shown that the hardness of self-organized copper films formed at friction in aqueous solutions of acids increases upon shifting from acetic to caproic acid.
