Abstract

To evaluate aligned multiwalled carbon nanotubes (MWNT) and dispersed MWNT for solid lubrication applications, unidirectional sliding friction experiments were conducted with 440C stainless steel balls and hemispherical alumina-yttria stabilized zirconia pins in sliding contact with the MWNT deposited on quartz disks in air and in vacuum. MWNT had superior solid lubrication friction properties and endurance lives in air and vacuum under dry conditions. The coefficient of friction of the dispersed MWNT was close to 0.05 and 0.009 in air and in vacuum, respectively, showing good dry lubricating ability. The real area of contact was minimized by the high elastic modulus of the MWNT, alumina-yttria stabilized zirconia, and quartz. This is an abstract presented at the World Tribology Congress III (Washington, DC 9/12-16/2005).
