| Outline of Final Research Achievements |
Ultra-precision diamond cutting tools show severe wear in turning of ferrous materials. In this study, we have investigated surface modifications of steels to improve their machinability. Carbides precipitated around grain boundaries suppressed the tool wear in turning of carburized steels. Additionally nitrides precipitated on grain boundaries have increased the effect of wear suppression in turning of nitrided stainless steels.
