Tribological properties of Ni–P-multi-walled carbon nanotubes electroless composite coating

Carbon nanotubes (CNTs) have super-strong mechanical characteristics and unique hollow nanotube structure and are believed as very ideal materials for fabricating the excellent composites. In this paper, tribological properties of Ni–P-CNTs composite coating prepared by electroless technique were investigated using a ring-on-block test rig. The results indicated that addition of CNTs would result in an increase in hardness of the composite...
