Outline of Final Research Achievements

Availability of the TiN-coated film deposited by Filtered Arc Deposition (FAD) method is investigated. In FAD method, the extremely smooth surface is formed without any droplets (macro particles) due to the magnetic filtering. The mechanical properties such as hardness, adhesion strength and friction coefficient of coated film depend considerably on the deposition conditions. The TiN-coated end mill has good mechanical properties such as hardness and adhesion strength when the bias voltage is -50 V with N2 flow rate of 20 cc/min, and this tool is effective in high speed milling of prehardened steel (JIS SUS420J2) than commercially available AIP and HCD (Hollow cathode discharge) tools.
