Effect of Surfactants on the Tribological Behavior of Organic Carbon Nanotubes Particles Additive under Boundary Lubrication Conditions

The tribological enhancement of nano-lubricant that consist formulated Eichhornia Crassipes carbon nanotubes (EC-CNTs) dispersed in base rapeseed oil using sodium dodecyl sulfate (SDS) and oleic acid (OA) as surfactants was conducted this study. experiment done high frequency reciprocating rig, applying 0.5 mass%, 1 mass% 1.5 EC-CNTs alongside 2% 5% the various sonicated for 25 minutes 50 respectively. use sonication to reduce agglomeration. outcome showed SDS yielded better results than OA, further revealed under time reduced solution agglomeration compared minutes. test on concentration effects based friction wear reduction, load carrying ability, lubricant film stability, scar micrograph mechanism particles. indicated inclusion nanoparticles substantially enhanced characteristics. However, pronounced recorded with EC-CNT counterpart lubricants. Friction reduction by were 65.4% 63.6% respectively against oil. exhibited excellent which achieved.
