Tribological application of carbon nanotubes in a metal-based composite coating and composites

Ni–P–carbon nanotube (CNT) composite coating and carbon nanotube/copper matrix composites were prepared by electroless plating and powder metallurgy techniques, respectively. The effects of CNTs on the tribological properties of these composites were evaluated. The results demonstrated that the Ni–P–CNT electroless composite coating exhibited higher wear resistance and lower friction coefficient than Ni–P–SiC and Ni–P–graphite composite...
