GOALI/IUCP: Design and Development of a Novel Technology for the Synthesis and Fabrication of Cubic Boron Nitride Composite Coating for Cutting Tools

本课题旨在研究和开发一种新型的复合技术，即立方氮化硼（cBN）粉末的静电喷涂（ESC）和氮化钛（TiN）相在cBN基体中的化学气相渗透（CVI）相结合，为cBN:TiN复合涂层刀具刀片的制备提供一种革命性的方法。该研究计划将由大学和一个工业伙伴合作执行。这项概念验证研究工作将提供一种独特的方法，通过保持与刀具应用相关的良好性能，在cBN- tin复合层中实现cBN的最大浓度。基础研究和应用技术开发的成功不仅将有助于cBN涂层工具产品的开发，而且将导致创新产品的出现。

This research project is to investigate and develop a novel hybrid technology, a combination of electrostatic spray coating (ESC) of cubic boron nitride (cBN) powder and chemical vapor infiltration (CVI) of titanium nitride (TiN) phase in the cBN matrix, a revolutionary method for the fabrication of cBN:TiN composite coated cutting tool inserts. The research program will be executed in collaboration between the University and an industrial partner. This proof-of-concept research effort will provide a unique way to achieve maximum concentration of cBN in cBN-TiN composite layer by maintaining good properties relevant to cutting tool application. The success of the fundamental study and applied technological developments will not only be instrumental in the development of the cBN coated tool product but will lead to innovative products.
