Collaborative Research: SGER: Feasibility of a New Nano-Composite cBN Coating Method for Next Generation Cutting Tools for Harsh Hard Machining

将探索开发新一代刀具涂层的新方法的可行性。这种方法基于超硬立方氮化硼(CBN)纳米颗粒与氮化钛(TiN)相基质的创新复合涂层，以及专门用于硬加工的基于科学的新刀具设计方法。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颗粒尺寸的团聚问题来发挥作用，并确定这种涂层工具是否可以在商业上竞争。这是一项由普渡大学和阿肯色州大学合作开展的研究项目。如果成功，这种方法可能会提供一种在刀具上合成保护性涂层的经济方法，比传统的化学或物理气相沉积成本低得多。这样的高性能刀具减少了更换刀具的频率，提高了生产率。

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.
