ABSTRACT
The present experimental study investigates to Tribological - behavior on Zinc Oxide (ZnO) nano particles used as an additive of SAE (20W-40) engine oil. The nanoparticles were synthesized using the Two-step process in the laboratory, were scatter in the volume concentrations of 0.01, 0.02, and 0.05 in the engine oil using an utrasonicator. The tests for finding to friction as well as a wear feature were conducted using a 4ball tribotester for the ASTM standard D4172, consisting Load of 40 kilo gram at 1200 revolution per minute rotation for testing time of 1 hour at the temperature at 75 °C. Then an experimental result revealed to addition of nano particles to the engine oil improves from friction and anti-wear properties to a great extent. In this case Coefficient of Friction (COF) and their corresponding Wear Scar Diameter (WSD) and Wear Surface Area (WSA) were reduced for the samples containing Nanoparticle additives than those without nano particles. The samples with nano particles also showed good stability over a period of 1 month.
