Abstract

It is known that diamond is not suitable for cutting of ferrous metals, ascribed to serious tool wear occurred in machining process. For the sake of studying the tool wear mechanism further, this paper presents thermal analysis method to discuss the chemical transformation of diamond with Fe catalysis. Raman scattering experiment was performed to identify the transformation of crystal structure of the diamond specimens. The surface wear morphology of workpiece was detected by scanning electron microscopy, and energy dispersive X-ray analysis was used to study the change of chemical composition. Experimental results revealed the law of graphitization and diffusion of single crystal diamond at elevated temperature in different gas environment.
