摘要：TiAlN/TiN multilayer PVD coated carbide is one of the dominant tool materials for the turning applications of Inconel 718 due to its high hardness, high wear resistance, and high thermal stability. The results of a thorough investigation on TiAlN/TiN multi layer PVD coated carbide inserts were presented for turning Inconel 718. The tool wear of the PVD coated carbide inserts were tested and analyzed at different cutting speeds from 50m/min to 90m/min and different feed rates from 0.1mm/r to 0.4mm/r. The wear patterns and wear mechanisms of PVD coated carbide were analyzed. Results show that the dominant wear patterns are rake face wear, flank wear, micro-chipping, coating delamination, notch wear, built-up edge and breakage. The main wear mechanisms are adhesion, diffusion, abrasive and oxidation.
