Implication

Experimental study demonstrates reduced friction and wear in polyalkylene glycol lubricants using Ti3C2Tx MXene, indicating strong potential for demanding tribological applications.

Key Points

To investigate the friction and wear performance of Ti3C2Tx MXene as an antiwear additive dispersed in polyalkylene glycol lubricant under reciprocating sliding conditions.
Prepared nanolubricants by dispersing Ti3C2Tx MXene in polyalkylene glycol (PAG) at mass fractions of 0.1 wt.% and 0.5 wt.%.
Evaluated coefficient of friction and wear under reciprocating sliding conditions compared to pure PAG oil.
Characterized metallic counterbody surfaces and tribofilm morphology using scanning electron microscopy.
The coefficient of friction decreased from 0.197 for pure PAG to 0.113 with 0.1 wt.% MXene and 0.142 with 0.5 wt.% MXene.
Both MXene nanolubricant formulations achieved substantial wear volume reductions ranging from 84% to 89%.
Scanning electron microscopy revealed the formation of protective MXene tribofilms that accumulated within asperity valleys and smoothed surface roughness.
