dc.description.abstract | In this study, ultra-fine grained Cu and Cu + carbon nanotube (CNT) nanocomposites were prepared through a processes combining flake powder metallurgy, hot pressing, and high-pressure torsion (HPT). The effects of grain refinement and CNT reinforcement on the microstructure, hardness, wear resistance, and corrosion behavior of the newly developed nanocomposites were investigated. The results indicated that the HPT process decreased the grain size of Cu and Cu + CNT by 67.7% and 68.1%, respectively, and increased their microhardness by 151% and 132%. The addition of CNTs substantially improved the tribological behavior of Cu by generating a mechanically mixed carbon- and oxide-rich layer. Moreover, polarization and electrochemical impedance spectroscopy tests revealed that the CNTs have a negligible adverse effect on the corrosion resistance of the Cu + CNT nanocomposites. The influences of the processing route and CNTs are discussed. Graphic Abstract: [Figure not available: see fulltext.] © 2021, The Korean Institute of Metals and Materials. | - |
