A Review on Effect of Addition of Nano Particles on Tribological Properties of Lubricants

Wear is the progressive loss of the material from the operating surface of machine due to relative motion between surfaces. The successful design of machine elements depends upon essentially on the understanding tribological principles like wear and friction. The lubricating oils are the blood of the machine’s operation, and the service life and economic effectiveness of the machine are relative to the quality, performance and reasonable use of the oils. Nanoparticles put into lubricating oils can improve the properties of extreme pressure, anti-wear and friction reducing. Efficiency and service life of the machine were also improved. In recent years, many scientific researchers have dedicated themselves to studying lubricating oil additives as an important project. In the present review paper, comparative study of tribological properties like anti-wear and friction reducing properties of nanolubrication oils are studied. In the studied papers nanolubrication oils are made by adding different nanoparticles like Cu, CuO, TiO2, CeO2 to different lubricating base oils/engine oils in varying proportions.
