Abstract

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