Abstract

DELGADO, Arnoldo E; GARCIA, Rafael G  and  APERADOR, William A. Study Lubricity of Sesame Oil with Copper Nanoparticles. Inf. tecnol. [online]. 2016, vol.27, n.6, pp.175-184. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642016000600018.

The lubricant power of extra virgin sesame oil with the addition of copper nanoparticles was evaluated by tests of preventive wear and extreme pressure. The performance of the vegetable oil as a lubricant was compared with a commercial hydraulic oil. The lubricity of the oils was evaluated by measuring wear scare diameter, last nonseizure load and the weld point. Experimental results indicate that the copper nanoparticles in dispersion act as both anti-wear and extreme pressure additives. It was found that a concentration of 1% copper nanoparticles dispersed in the base oil has better lubricant performance than commercial hydraulic oil.

Keywords : sesame oil; copper nanoparticles; lubricant; tribology; anti-wear additive.
