Abstract

The cutting experiment for nickel-based supper alloy Inconel 718 was performed by using two different coated inserts, which studied the wear morphology and wear mechanism of the tools and analyzed the effect on tool life from different coating. The results showed that when continuous cutting is performed under same cutting conditions, the capability of WSM10 to resist oxidation and adhesive is higher than TS2000, and the tool life of WSM10 is longer than TS2000. The reason why WSM10 has a better cutting performance than TS2000 is related to the coating material. Comparing with the TiN coating of TS2000 surface, the A1203 coating of WSM10 surface has a higher hardness, better chemical stability and oxidation resistance capability. The study provides a useful reference for the selection of cutting tools which used for machining Inconel 718.
