Research on Surface Modified Micro/Nano-MgO Particles Improve Tribological Characteristics of Lubricating Oil
This paper applies the sol-gel method (Sol-Gel) ，uses Poly Vinyl pyrrolidone (PVP) as dispersant，oleic acid as modifier to prepare and modify micro/nano-MgO particles. The characterization results of micro/nano-MgO particles by using XRD and SEM verified that micro/nano-MgO particles prepared above are FCC and the average particles size is 50nm. In the process of friction and wear experiment, the results show that at the significant effect of anti-friction and anti-wear is obtained after adding micro/nano-MgO particles in the 4012 marine lubricant. Especially under higher loads, the friction-reducing effect is more prominent.
