Study on the Coated Tool Wear Mechanism of High Speed Milling Ni-Base Superalloy GH625

Abstract:

The experiments of high speed milling Ni-base superalloy GH625 by using two types of the coated cemented carbide tools at home and abroad, using the scanning electron microscopy (SEM) to observe the tools wear morphology, analyzing the worn surface elements distribution by energy spectrum analysis (EDS) and the main wear mechanisms of the tools. The results show that adhesion, oxidation and diffusion are the main wear mechanisms in initiative wearing stage of the domestic coated tools. And the main wear mechanisms of the imported coated tools are adhesion, oxidation, diffusion and coating spallation.
