AB This Doctoral Thesis presents new designed nanolubricants as potentialsubstitutes of conventional lubricants. Hexagonal boron nitride nanoparticles, graphene nanoplatelets, iron oxidenanoparticles (synthetized from iron mine sludge), three phosphonium ionic liquids and two polyalphaolefin baseoils (PAO32 and PAO10) were the materials selected. The techniques used in the characterization of nanoparticles,base oil, ionic liquids, and the worn surfaces from the tribological tests were Raman, SEM, FTIR, HRTEM, XRD or3D profilometry. Viscosity, density, viscosity index, stability and tribological behavior (friction and wear) of designednanolubricants were studied. Most of them improved the overall properties of PAO32 40 % reduction in friction and99 % in wear being stable up to 240 days.
