Co-W alloy/multiwalled carbon nanotube (MWCNT) composite films were fabricated using an electrodeposition technique and their microstructures were characterized. A citrate bath was used as the Co-W alloy/MWCNT composite plating bath. A compact Co-W alloy/MWCNT composite film having uniform distribution of MWCNTs without cracks was electrodeposited by adjusting the pH and current density. Frictional properties of the Co-W alloy/MWCNT composite film were evaluated using a ball-on-disk method at room temperature as well as at elevated temperatures (similar to 300 degrees C) without any lubricant. The coefficient of friction of the Co-W alloy/MWCNT composite film was clearly lower than that of a Co-W alloy film with the same tungsten content at room temperature. The coefficient of friction of the Co-W alloy/MWCNT composite film increased with increasing temperature. However, the coefficient of friction of the Co-W alloy/MWCNT composite film was lower than that of a Co-W alloy film with the same tungsten content at elevated temperatures.
