Evaluation of anti-wear properties of automobile lubricant with different additives using thin layer activation technique

Thin layer activation technique (TLA) has been used for measurement of wear rate of disc gears under lubricated condition. A synthetic base lubricant was blended with four different types of additives, such as, hexagonal boron nitride (h-BN), molybdenum disulphide (MoS2), graphite and copper nanoparticles (Cu np). The wear rate of the disc gear was measured in presence of individual lubricant formulations. The aim of the current study is to examine the effect of different additives on anti-wear behavior of the synthetic heavy duty gear lubricant using TLA technique. The lubricant formulation containing h-BN showed best anti-wear property among all the formulations and the wear rate in this case was found to be minimum from all other cases.
