Abstract
The synthesis and characterization of magnetic nanoparticles have been widely studied due to their applications in several areas of knowledge. Obtaining nanomaterials as additives with specific properties for industrial lubricating oil has been getting many expectations that can minimize tribological problems, in addition the friction and wear handle failures in equipment and machinery. For iron oxide nanoparticles, the most important variations are caused by the observed phenomena that are intrinsic or become dominant in nano-scale. These phenomena include confinement due to the size, predominance interface phenomena and quantum phenomena. However, the study of these magnetic phenomena of nanoparticles is connected with type and morphology, directly influenced by the synthesis. Therefore the aim of this study is to synthesize the nanoparticles by microwave power 300W, in two different times and temperatures, 0.5 minutes and 2.0 minutes, 55° C and 95 ° C, respectively, obtaining them with different physical and chemical properties, also be characterized by X-Ray Diffraction and correlated with crystallite size, time, kinetic energy study nucleation and about how the magnetic nanoparticles can act as antiwear additives.

Reported that nanofluids can be used in several areas as heat-transfer nanofluids, surfactant, chemical and environmental nanofluids, bio, pharmaceutical and medical nanofluids and tribological nanofluids, there’s the focus this paper.Nanofluids are a class of fluids which consist of a base fluid with nanosized particles (1–100nm) suspended within them, can be a lubricant
Summary
RESUMEN La síntesis y caracterización de nanopartículas magnéticas han sido ampliamente estudiadas debido a sus aplicaciones en diversas áreas del conocimiento. The ferrofluids can be used like nanofluids of aplication tribological, so there are many studies on automotive lubrication applications, surface modified nanoparticles stably dispersed in mineral oils are reported to be effective in reducing wear and enhancing load-carrying capacity. Results from a research project involving industry and university points to the use of nanoparticles in lubricants to enhance tribological properties such as load carry incapacity, wear resistance, and friction reduction between moving mechanical components. Such results are encouraging for improving heat transfer rates in automotive systems through the use of nanofluids
