Molybdenum Disulfide Nano- based lubricant

The present invention discloses a nanoparticle suspended lubricant that helps reduce costs, extended tool life and improve performance of machining process. Accordingly, the present invention provides a nano-based lubricant for use in machining comprising molybdenum disulphide (MoS2) nanoparticle and mineral oil wherein the nano-based lubricant is free from additive including phenol and chlorine, wherein the mineral oil has a concentration of 0.5% and wherein the molybdenum disulphide (MoS2) nanoparticle has a particle size ranging from 20 nm to 60 nm. The molybdenum disulphide (MoS2) nanoparticle is mixed with mineral oil having 0.5% concentration by way of sonication method.
