Abstract
The research team of this project comprises Dr Edmund H M Cheung and Dr Lawrence K Y Li from the Department of Manufacturing Engineering and Engineering Management. The basic objectives of the project are to:
(1) fabricate novel nanocomposite coatings (eg. nc-TiN/nc-AlN, nc-WN/a-SiNx, nc-TiN/nc-BN and nc-TiN/a-CNx) with hardness in excess of 40 GPa;
(2) modify the nature of film/substrate interface in order to optimize adhesion of coatings on tools and other components;
(3) obtain basic metal cutting parameters by performing statistically designed and planned orthogonal cutting tests on work-piece materials considered most relevant by target end users; and
(4) provide high quality PVD coating services and consultancies on specific processes and products to local industries.

It is envisaged that this new research and development program will lead to improved knowledge of these novel materials, and provide practical techniques of how they can be synthesized and gainfully used by manufacturing industries in Hong Kong and the region. This project received financial support under the Innovation and Technology Fund of the HKSAR Government.

簡介
本項目由製造工程及工程管理學系的張漢民博士及李國恩博士共同開發。研究計劃的主要目的包括：
(1) 製備新型的納米複合塗層 (例如nc-TiN/nc-AlN, nc-WN/a-SiNx, nc-TiN/nc-BN及nc-TiN/a-CNx), 其硬度超過40 GPa;
(2) 改善膜與基體之間的界面性能, 提高塗層在工具及其它工件上的結合力;
(3) 通過在實際工件上進行統計正交試驗, 獲得基本的金屬切削參數;
(4) 向本港工業界就特殊工藝和產品方面提供高質量的PVD塗層服務和咨詢。

可以預計, 這一新的研究與開發計劃將有助於加深對這些新型材料的了解, 並為香港製造業提供塗層合成及有效使用的實用技術。本研究獲得香港政府的創新及科技基金資助。
