| 发明名称 | Cutting tool with multi-layer coating | ||
| 摘要 | The invention relates to a cutting tool comprising a main part and a multilayer coating applied thereon. A first layer A made of a hard material is applied on the main part, said hard material being selected from titanium aluminum nitride (TiAlN), titanium aluminum silicon nitride (TiAlSiN), chromium nitride (CrN), aluminum chromium nitride (AlCrN), aluminum chromium silicon nitride (AlCrSiN), and zirconium nitride (ZrN), and a second layer B made of silicon nitride (Si3N4) is applied directly over the first layer A. | ||
