In this study the performances of some commercially available carbide inserts when machining Hastelloy C-22HS was investigated under scanning electron microscopy (SEM) for wear mechanisms and other microstructure defects. Carbide inserts coated with TiCN/TiN and TiALN/TiN experienced severe intergra...
