The objective of this research project is to investigate novel embedded solid lubricant cutting tool coatings for applications in machining and manufacturing processes. The research concept is to use lithographic patterning methods to create two-component coatings. One component of the coating will be a hard compound that is highly wear resistant, and the second component, embedded in the hard compound, will be a solid lubricant material. This approach will alleviate a common problem encountered in the use of solid lubricant coatings, namely short wear life. This research project will investigate methods for fabricating and patterning these coatings, the mechanical and thermal stability of the coatings, and the operative tribological mechanisms that determine their frictional behavior. In addition to laboratory analysis and tribological testing of the coatings, a key component of the research will be to apply the coatings to cutting tools and perform instrumented metal cutting tests.The ability to fabricate engineered metallic components using cutting and forming processes is integral to a wide range of manufacturing processes. The application of coatings to cutting tools and metal forming dies can enhance tool life and reduce the energy expended in overcoming frictional forces. The use of liquid lubricants also reduces friction, however, environmental and health issues, as well as economic concern over the cost of their treatment and disposal has made the use of solid lubricants more attractive. This research program will promote the development of high wear-resistance coatings incorporating solid lubricants. The use of these coatings could lead to a reduction in environmental waste, as well as reducing the costs of waste fluid treatment and disposal. The program also aims to improve technical awareness about engineered coatings by developing portable educational modules that can be used at the high-school level.

本研究项目的目的是研究新型嵌入式固体润滑剂刀具涂层在机械加工和制造过程中的应用。该研究的概念是使用光刻图案化方法来创建双组分涂层。涂层的一个成分将是高度耐磨的硬质化合物，第二个成分嵌入硬质化合物中，将是固体润滑材料。这种方法将缓解固体润滑剂涂层使用中遇到的一个常见问题，即磨损寿命短。本研究项目将研究这些涂层的制备和图案化方法、涂层的机械稳定性和热稳定性，以及决定其摩擦行为的摩擦学运行机制。除了对涂层进行实验室分析和摩擦学测试外，这项研究的一个关键组成部分将是将涂层应用到刀具上，并进行仪表化金属切割测试。使用切割和成形工艺制造工程金属部件的能力是广泛的制造工艺所不可或缺的。在刀具和金属成形模具上应用涂层可以提高刀具寿命，降低克服摩擦力所消耗的能量。液体润滑剂的使用也减少了摩擦，然而，环境和健康问题，以及对其处理和处置成本的经济担忧，使得使用固体润滑剂更具吸引力。这一研究计划将促进含固体润滑剂的高耐磨涂层的发展。使用这些涂料可以减少环境废物，并降低废液处理和处置的成本。该计划还旨在通过开发可用于高中水平的便携式教育模块来提高对工程涂层的技术认识。
