Abstract

The automotive sector is demanding higher specifications to achieve maximum efficiency; in this sense a new generation of lubricants with higher thermo-oxidative stability and superior tribological properties is being explored. The formulation of nanolubricants based on the nature of different nanomaterials is one of the most recent approaches, with several gaps to cover, such as dispersion stability, related to the compatibility of proposed nanomaterials with conventional additives and baseoils used in lubricant formulation. This study evaluated the effect of ZnO nanomaterial dispersed in a commercial engine oil using two different approaches; the use of surfactant and nanomaterial surface functionalization to promote higher stability and lower cluster size. Experimental evidence shows a synergetic effect between the tribological protection mechanism and the antioxidant properties in the lubricant. The effect of nanoparticle cluster size, functionalization level, and nanomaterial content are presented.

摘要

汽车行业对更高规格的要求以实现最大效率；从这个意义上说，正在探索新一代具有更高热氧化稳定性和卓越摩擦学性能的润滑剂。基于不同纳米材料性质的纳米润滑剂配方是最新的方法之一，有几个方面需要涵盖，例如与所提出的纳米材料与润滑剂配方中使用的传统添加剂和基础油的兼容性相关的分散稳定性。本研究使用两种不同方法评估了分散在商用发动机油中的ZnO纳米材料的效果；使用表面活性剂和纳米材料表面功能化来促进更高的稳定性和更小的团聚尺寸。实验证据表明，摩擦学保护机制与润滑剂中的抗氧化性能之间存在协同效应。文中呈现了纳米颗粒团聚尺寸、功能化水平和纳米材料含量的影响。
