ABSTRACT
Lubricating greases are prepared by dispersing simple soaps and complex soaps of lithium, calcium and aluminium in mineral oils. Greases are used under extreme conditions such as high temperature, extreme pressure and shock loading etc. To perform these objects satisfactorily the lubricating greases must have dropping point well above the operating temperature of machinery parts. Consistency and dropping point of lubricating greases are considered as an important property to improve capability of grease. These properties are dependent on type of soap and additives used during formulation Molybdenum Dithiophosphate (MoDTP) can be used as extreme pressure and anti-wear additives for lubricating grease. MoDTP has significant effect on consistency and dropping point of lubricating grease. In recent time molybdenum as friction modifier achieve energy saving in the systems.
