Application of novel soft solid lubricant coatings on turning tools for sustainable and high-performance machining of INC 718 alloy: A new efficient fluid-free method

This study introduces the application of a novel class of soft solid metallic lubricant coatings on hard-coated cutting tools to enable high-performance, fluid-free machining of Inconel 718. By employing a novel in-situ coating technique, the Al-Si lubricant coating was applied to commercially available AlTiN-coated tools within a CNC machine in just seconds. The Al-Si-coated tools demonstrated significantly improved performance in dry …
