1.INTRODUCTION
Nowadays nanoscience is one of the most expansively creatingspheresofworld’sscienceanditsachievementscan be utilized in special areas of science and technology. For instancenanomaterials,presentintheshapeofsoknownas nanostructures (nanotubes, nanowires, nanopowders and others) that are wider and wider used in many fields of human undertaking - from most cancers cure thru to engineeredtextilesorelectricitystoragetorocketpropellant andexplosives.Anditispastadoubtthatseveranewfields ofnanostructuressoftwarewilloccurinthenearesttime.One ofthemlookstobetheunexploredregionofnanostructures useascomponentsenhancinghomes(especiallytribological) oflubricatingorreducingoils.

1.2 Basic Modes of Lubrication
In lubrication, two contacting surfaces which haveactionrelativetoeachdifferentareseparatedbyway ofaexcessivestrainmovieof lubricant. Based on theapproachofgrowingtheexcessivestressmovieof lubricant between the contacting surfaces, the lubrication canbecategorizedinto4types
•Hydrodynamic lubrication
•Hydrostatic lubrication
•Electrohydrodynamic lubrication
•Solidmovielubrication
2.PROBLEM STATEMENT
The traditional lubricants used for a number mechanical structures consist of specific sorts of traditional additives. Thecomponentsassisttoenhancethelubricatingandantiwear homes of the lubricant. But these traditional componentshavesureboundariesatheavyloads.Theyare nownotinapositiontopreservetheiruniquehousesandfor that reason exhibit negative lubricating and anti-wear residences at these heavy loads. So there have to be improvement in the components so as to make bigger the workingvaryofthelubricantbyusingtheusageofMoS2and SiO2 nanoparticles for my part and with the aid of mixing thematarangeofattentionofnanoparticles.
