Development and characterization of Cu/MWCNT composite prepared by electrodeposition technique

Abstract

Multi walled carbon nanotube (MWCNT) reinforced copper matrix (Cu/MWCNTs) nanocomposites were successfully fabricated by electrodeposition technique using DC-Power source. With various concentrations of CNT, microstructural, micro hardness, tensile stress, and Electrochemical studies were done. The Cu/MWCNT nanocomposites at the highest concentration of 450mg/l exhibited ∼25% and 47% higher tensile strength and Vickers microhardness respectively than that of the pure Cu. Electrochemical AC-impedance and Tafel polarisation analyses confirmed that the corrosion potential (E<inf>corr</inf>) and corrosion current density (i<inf>corr</inf>) of nanocomposites at 450 «mg/l obtained about 190 »mV SCE and 1.09 μ A/cm2 respectively in 3.5 wt.% NaCl solution. © 2020 Author(s).
