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.

将探讨开发新一代刀具涂层的新方法的可行性。该方法基于一种创新的超硬立方氮化硼（cBN）纳米颗粒与氮化钛（TiN）相基体的复合涂层，以及一种基于科学的刀具设计新方法，专门用于硬加工。研究人员建议通过解决亚微米颗粒尺寸的团聚问题来探索新的基于静电的涂层方法是否有效，并确定这种涂层工具是否具有商业竞争力。这是普渡大学和阿肯色大学的合作研究项目。如果成功，这种方法可能提供一种经济的方法来合成刀具上的保护涂层，比传统的化学或物理气相沉积便宜得多。这种高性能的刀具减少了刀具更换的频率，提高了生产率。
