Abstract:
Nano additives are generally blended with the base lubricant oil, to enhance the lubricant characteristics. In this research, nano additives of SiO2, Al2O3 and TiO2 are blended with the base SAE10W30 oil with different proportions of mixture. 27 samples with three different levels of mix of nano additives are identified using factorial design of experiment. The experimental outcomes for the selected six characteristics of interest of specific wear rate, co-efficient of friction, kinematic viscosity, density, flash point and fire point are determined. Using Taguchi method, the optimal values for each property of lubricant are identified. Also, the optimal mix of all three nanoadditives is determined for all the desirable level of six properties of lubricant using multi-objective polynomial program in this research. The optimal mix is identified as 0.05 wt.% of SiO2, 1 wt.% of TiO2, and 0.3 wt.% of Al2O3.
