Wear performance investigation of PVD coated and uncoated carbide tools during high-speed machining of TiAl6V4 aerospace alloy

Selection of hard PVD coatings for the machining of Ti6Al4V alloy should be based on the dominant tool wear mechanism and tribological phenomena occurring at the chip-tool-workpiece interface. The present work investigates the effect of AlTiN and CrN hard coatings on the wear performance of cemented...
