** Don State Technical University, Russia Received April 26, 2007 Abstract — Applying a cooper galvanic coatings from a heatly with minor (2 = 0.03) addition of Nmethylpyrrolidone makes the latter much more permeable and capable of displaying the inhibition of the base metal. The former effect is dominant at the monomer concentrations 105 < < 102 mol/l, while the latter effect is dominant at > 102 mol/l. The best electroplates in appearance and adhesion were obtained for the metal–additive ratio 1 : 10. According to AFM data, the grain size in this coating is comparable with nanoparticles. Friction tests showed that such copper polymer coatings can be used as a long-lived grease under dry friction conditions. PACS numbers: 82.45.Qr, 82.45.Gz DOI: 10.1134/S2070205109010122
