The feasibility of a novel approach for developing a new generation of cutting tool coatings will be explored. This approach is based on an innovative composite coating of superhard cubic boron nitride (cBN) nano-sized particulates with titanium nitride (TiN) phase matrix along with a science-based new methodology for cutting tool design, specific for hard machining. The investigators propose to explore if the new electrostatic-based coating method will work by resolving the agglomeration problem for submicron particle sizes, and to determine if such coated tools can compete commercially. This is a collaborative research program to be performed by Purdue University and University of Arkansas.If successful, this approach may provide an economical way to synthesize protective coatings on cutting tools, far less expensive than traditional chemical or physical vapor deposition. Such high-performance cutting tools reduce frequency of tool replacement and improve productivity.

将探讨一种新一代新一代切割工具涂料的新颖方法的可行性。 这种方法基于用氮化钛（TIN）相位基质的超智立方硼化硼（CBN）纳米级颗粒的创新复合涂料以及一种基于科学的切割工具设计的新方法，用于硬加工。 研究人员建议探索新的基于静电的涂层方法是否会通过解决亚微米粒径的聚集问题来工作，并确定此类涂层工具是否可以在商业上竞争。 这是一项合作研究计划，由普渡大学和阿肯色大学进行。如果成功，这种方法可能会提供一种经济的方式来合成在切割工具上的保护涂料，比传统的化学或物理蒸气沉积便宜得多。 这种高性能切割工具降低了工具更换的频率并提高生产率。
