Abstract
Present study was carried out for knowing how nanotechnology can be employed for improving the performances in tribology. A significant number of investigations have been reported on the effect of nanoparticles as oil additives. The wear and friction tests were carried on four ball oil tester using ZDDP, NiO and MoS2 nanoparticles in 1wt% combination with mineral oil to provides the reduction in friction and wear. Much of the research suggests that even up to 1% concentrations of such particles are instrumental in reducing wear and friction. Nanoparticle additives have proved to be promising for development of Tribological properties of mineral oil. The tribological properties of typical engine oil like SAE15W40 mineral oil added with nanoparticle additives were studied and then experimental analysis was done. Investigations were performed on oil having concentrations of Zinc Dialkyl Dithio Phosphate, Molybdenum Disulfide and Nickel Oxide nanoparticles and their combinations to find that anti wear properties are improved. The evaluation of the tribological behavior pertaining to friction was determined using four ball oil testing machine TR-30L containing combination of above described nanoparticles together in base oil showed the most promising results.
Highlights
Recent research papers have reported that the addition of nanoparticles to lubricant is effective for the reduction of wear and friction in mechanical systems
Branded mineral oil (SAE 15W40) and nano-oil samples were prepared by diffusing various concentrations of 24 to 34nm sized NiO, ZDDP and MoS2 nanoparticles in conventional diesel engine oil
Coefficient of Friction (COF) In this work the frictional torque was recorded torque values and the coefficients of friction of the lubricants were determined from the graphs indicated from the software
Summary
Recent research papers have reported that the addition of nanoparticles to lubricant is effective for the reduction of wear and friction in mechanical systems. Limiting vitality lost through grating builds the effectiveness of machines In this manner, with regards to vitality proficiency, the noteworthiness of decreasing erosion can't be overemphasized. One of the study suggested that Ni-MoS2 nano sheets in gear oil helps in forming of a linear tribo film which increases Wear resistance and load carrying capability[6]. The reports on the tribological performances of ZDDP-MoS2 and NiO nanoparticles are fairly limited especially on the formation of MoS2 lubricating film [8].
