Abstract

New applications for titanium nitride coating are being developed continuously. On cutting tools, TiN coating has extended lives by 300 to 800% and more. Large increases in cutting speeds and feeds have been achieved and less cutting edge removal is necessary in resharpening. In addition, by allowing faster metal removal rates, extended tool life lowers the tool cost per piece. The higher productivity increases the return on the machine, direct labour and supervision costs. Ionisation-assisted physical vapour deposition (PVD) techniques at comparatively low temp. are gaining acceptance. Although the UK has been comparatively slow to take up these new techniques, the picture is changing. Holt Bros Treatment of Halifax has been researching a new evaporative process for TiN deposition in a number of industrial tooling applications, and has commissioned the UK vacuum equipment manufacturer, Tecvac of …
