Synthesis of Coated Nickel Nanoparticle and its Application as Nanolubricant
Author(s):
Abstract:
Lubricants and their additives are important due to their properties which allow longer life and are used widely as an in tribology. In recent decades, they have become more important because of environmental affairs. There are a lot of nanoparticles which can decrease this problem, but they are not suitable enough as their solubility and dispersion in lubricants is low. The best way is using organic coating agent to overcome this problem. In this paper, we synthesized coated nickel nanoparticles by using a micro-emulsion method, sodium dodecylsulfate as a surface active agent in water and ethanol as solvents. Some effective parameters were considered such as the type and quantity of coating agent. The physical properties such as particle size and specific surface area were determined by analytical instruments (TEM, BET, and XRD). The synthesized nickel nanoparticle has a spherical morphology. The particle size is between 7-13 nm and its special surface area is 30 m2/gr. Antiwear properties of nickel nanoparticles in base and multigrade oil were also determined via four ball and Falex tests.
