Abstract
For the application of milling ductile cast iron (FCD60), effect of microstructure and composition of substrate on cutting performance of cemented carbide tools coated with TiC by 2μm thickness were studied. It was suggested that the properties of coatings including adherence force to the substrate did not change, even when the structure and composition of substrate, and the surface-flatness of coatings were varied under a fixed content of binder. It was found that cutting performance of coated tools became superior, as the carbide grain size of substrate decreased.
