The objective of this collaborative research project is to study the mechanism of deformation of active molybdenum disulphide lubricant nanoparticles, integrated with organic molecules. The plastic deformation, and thus formation of a tribofilm, will be studied particularly when introduced in minimum quantity lubrication grinding and deep hole drilling. The technical approach to seek the objective necessitates first to study physical, chemical and tribological properties of active lubricant nanoparticles compatible with base fluids used in machining. In the next phase of this study the role of concentration and quantity of nanolubricant formulations, depth of cut, speed and number of machining passes will be investigated. The outcome will be assessed experimentally and partly theoretically using various in situ and ex situ parameters such as cutting forces, tool wear, surface finish and integrity of the workpiece, nano and micro structure, location, distribution and chemistry of the triobofilm, and size and chemistry of debris for studying the role of tribofilm in reducing cutting forces, increasing tool life and providing better surface quality of the machined workpiece. Additionally, one study will address understanding the transient evaporation of oil molecules integrated in nanoparticles and their subsequent role as an effective vehicle for heat transfer at the machining interface.The broad impact of this research is in facilitating the replacement of recirculating lubrication systems, which are sources of performance variation and significant waste streams. In addition, it is expected there will be energy savings and an increase in productivity at low cost in the most demanding machining applications. Further, this research is an example of how recent investment in nanomanufacturing in the United States can significantly benefit traditional machining and manufacturing industries to increase productivity in a range of infrastructure-related manufacturing industries. Training students in this nanotechnology will be an important component in the facilitation of a new generation of innovation.

该协作研究项目的目的是研究与有机分子集成的活性钼润滑剂纳米颗粒变形的机理。将研究塑性变形，从而形成互环膜，尤其是在以最小数量润滑研磨和深孔钻孔中引入时。寻求目标的技术方法首先需要研究与加工中使用的基础流体兼容活性润滑纳米颗粒的物理，化学和摩擦学特性。在本研究的下一阶段，将研究浓度和纳米化制剂，切割深度，速度和加工次数的作用。结果将在实验和理论上通过各种原位和原位参数在实验和部分上进行评估，例如工具磨损，表面表面以及工件，纳米和微型结构，三ob胶的位置，分布和化学的位置，分布和化学，以及debris的大小和化学的分布和化学，以及在改善工具中的工具效果，以改善工具的效果，并改善了工具的效果，并改善了工具的效率。此外，一项研究将探讨了解纳米颗粒中集成的石油分子的短暂蒸发及其随后作为在加工界面上进行传热的有效工具的作用。这项研究的广泛影响在于促进循环润滑系统的替代，这是性能变化和大量废物流的来源。此外，预计在最苛刻的加工应用中，将会节省能源和生产率的提高。此外，这项研究是一个例子，说明了美国最近对纳米制造的投资如何显着使传统的加工和制造业有益于提高与基础设施相关的制造业的生产率。培训这种纳米技术的学生将是促进新一代创新的重要组成部分。
