Characterization and machining performance of a chipping resistant ultra-soft coating used for the machining of Inconel 718

Inconel 718 is widely used in the aerospace industry due to its excellent mechanical properties, such as high corrosion and heat resistance and great strength at elevated temperatures. Unfortunately, the poor machinability of this alloy still presents a major challenge for manufacturers. Developing different types of tool coatings is a common method for enhancing the machinability performance of this class of materials. Almost all of the …
