Cubic boron nitride (cBN) is currently the hardest material for ferrous material machining. The Center of Super Diamond and Advanced Film (COSDAF) at CityU has successfully fabricated a stable cBN hard nanocoating for diamond. The next step is to form a team with experienced industry experts to make a cBN coating machine for industrial applications. cBN (80GPa) outperforms all regular hard coatings (28-40GPa) presently used in industry. This helps to at least double tool life and reduces production costs. We will serve advanced industries in the Greater Bay Area, and then the national and global markets. Preliminary estimates indicate a substantial gross profit for cBN coating machines. Our target is to sell more than 200 units within five years.
The aim of this project is to make a prototype cBN hard coating machine with the support of seed and angel funds. The project is set to be completed within 18 months. We believe that cBN hard coating marks a revolution in the coating industry and will have a major impact on the hard coating industry.
