The effect of different type of additives on friction and wear of MNR grease

Grease typically has a base of mineral or synthetic oil, a thickener, additives, and fillers. The tribological performance of grease depends on the viscosity of the base oil and the type and concentration of thickening agent used. Grease lubricants are used in many different parts of automobiles, in...
