Abstract:

We report on the investigation of the frictional properties of solid lubricants based on carbon nanotube (CNT) composites. Self-lubricating CNT composites were created by electrodepositing molybdenum disulfide (MoS₂) or silver (Ag) on multiwalled carbon nanotubes (MWNTs). MWNT/MoS₂ was found to display a lower friction coefficient both in humid (∼0.16) as well as dry (∼0.05) air and was able to sustain its frictional properties under non-humid/humid cycled environments. Similarly, the tribological properties of CNT/Ag composites were found to be improved in comparison to their constituent materials both at 25 °C and at 500 °C. These results show that combining CNTs with other solid lubricants may be a viable approach for the creation of a new class of adaptive tribological coatings where strength is provided by the CNTs, and lubrication is provided by graphite (created when CNT surfaces are worn) or by additional solid lubricants.
