| 摘要 |
The present invention relates to a cutting tool with a base body and a multilayered coating applied to it, wherein at least two layers of the multilayered coating, arranged one on top of the other, contain or consist of metal oxide of the same metal or of different metals. To provide cutting tools that are improved over the prior art, it is proposed according to the invention that the at least two metal oxide layers arranged one on top of the other are produced one after the other by different PVD processes, selected from i) reactive magnetron sputtering RMS, ii) arc vapour deposition (arc-PVD), iii) ion plating, iv) electron-beam vapour deposition and v) laser ablation, wherein modifications of the respective processes i) to v) do not constitute different PVD processes. |
