Protection of the Surface of Parts in Friction Units of Machines from Corrosion Using the Method of Finishing Antifriction Nonabrasive Treatment

The study is devoted to the production of protective adhesive copper- and aluminum-containing film coatings applied to steel 45 by a friction-mechanical method using a ductile metal rod tool. The work examines the interaction of films (copper-containing and aluminum) deposited on the surface of test samples using the finishing antifriction, nonabrasive treatment method. The properties of copper as a sublayer for the deposition of other ductile metals were studied. During the experiment, information was obtained about the conditions necessary for applying a continuous copper sublayer, the change in the weight of a steel sample before and after applying films of soft metals to it (including in several layers). The resulting composite coatings possess increased wear resistance, anticorrosion properties and a reduced coefficient of friction of bodies.
