The present investigation is focused on the tribological behavior of hybrid aluminium metal matrix composite (h-AMMC) sliding against cast iron (CI), under the surfactant assisted MWCNTs-in-oil lubricant. For this purpose, the MWCNT-in-oil lubricants were prepared in the presence of a non-ionic surfactant. The friction-wear results reveal that the surfactant assisted MWCNT-oil dispersions with an optimized concentration of surfactant significantly improve the friction-wear behavior for composite-cast iron contacts. Inherent properties of MWCNTs, better thermophysical and dispersibility characteristics of nano-dispersions, shear sliding of micellar structures under friction action and formation of protective tribo-layer are the prominent factors that responsible for improvement in lubricity and tribological performance. Characterization of the worn-out surfaces of h-AMMC is carried out using various techniques such as scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), surface roughness testing and Raman spectroscopy. The study reveals some interesting insights on the performance of surfactant assisted MWCNT-laden lubricants, which might be connoted for the future development of the lubricants to be used in the industrial applications.
