Abstract
The friction and wear behavior of Cu-matrix composite reinforced by carbon nanotubes (Nanotube/Cu composite) were investigated. By scanning electron m icroscopy (SEM) and X-ray diffraction (XRD), the worn surfaces and the worn chips were analyzed. The volume fraction of nanotubes is a main factor for the decrease of the wear rate of The Nanotube/Cu composite, which is assoc iated with carbon nanotubes forming a protective oxide film on the sliding surface of the specimen. The optimum nanotubes content is 12-15%. Both the coefficients of friction and weight loss of the Nanotube/Cu composite are l ower than those for Cu-matrix composite reinforced by carbon fiber (CF/Cu) owing to the much high intensity of nanotube.
