Deposition of Al-Sn nanostructured coatings on aluminum surface using electrospark alloying and their wear resistance under lubricated friction

Abstract

Under certain modes of electrospark alloying (ESA) of aluminum surfaces using the Al-Sn tool-electrode (TE), nanostructuring of the manufactured surfaces occurs owing to the formation of SnO2 fibers. Examining the tribological properties of these surfaces in a friction couple with a counterbody made of hardened steel showed that the wear of the counterbody during the friction in oil exceeds by an order of magnitude and above it the wear of such surfaces.
