Modification of metal surface with carbon nanotubes

Nickel composites containing carbon nanotubes were prepared by codepositing carbon nanotubes suspended in an electrolyte with growing nickel during electrodeposition. The microstructure of the coatings has been examined by electron microscopy, and the wear properties and corrosion resistance of the coatings were tested. The results show that the carbon nanotubes are uniformly dispersed in the coatings which have excellent wear resistance and corrosion resistance. This was due to the carbon nanotubes having super-strong mechanical properties and self-lubrication.
