Multilayer structured coatings for cutting tools |
| 摘要 |
In one aspect, cutting tools are described having coatings adhered thereto which, in some embodiments, can demonstrate desirable wear resistance and increased cutting lifetimes. A coated cutting tool described herein comprises a substrate and a coating adhered to the substrate, the coating having a multilayer structure including a plurality of structural units each comprising a bonding layer and an adjacent alumina layer, the alumina layer having a thickness of less than 0.5 μm and the bonding layer having a thickness less than 1 μm, the bonding layer comprising TiCN and TiAlOC. |
