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

将探索开发新一代切削刀具涂层的新方法的可行性。 这种方法是基于一种创新的复合涂层的超硬立方氮化硼（cBN）纳米尺寸的颗粒与氮化钛（TiN）相基质沿着与科学为基础的新方法的切削刀具设计，具体的硬加工。 研究人员建议探索新的基于静电的涂层方法是否能解决亚微米颗粒尺寸的团聚问题，并确定这种涂层工具是否能在商业上竞争。 这是一个由普渡大学和阿肯色州大学合作进行的研究项目。如果成功，这种方法可能提供一种经济的方法来合成切削工具上的保护涂层，远比传统的化学或物理气相沉积便宜。 这种高性能切削刀具减少了刀具更换频率并提高了生产率。

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.
