A coated tool has a substrate and a hard material coating deposited on the substrate. The hard material coating has a layer structure in the following order, starting from the substrate: a titanium nitride layer, a titanium boron nitride transition layer, and a titanium diboride layer. The titanium boron nitride transition layer has a boron content that increases from the titanium nitride layer in the direction of the titanium diboride layer. The boron content does not exceed 15 at %.

Coated tool

A tool for machining is made from a hard-metal, cermet or ceramic base material and a single-layer or multi-layer hard material coating on the base material. An additional coating of one or more metals from the group of aluminum, copper, zinc, titanium, nickel, tin or base alloys of these metals is applied to the hard material coating.

Tool for machining

A cutting tool for metal material processing has a hard metal body and a multi-layer coating applied to the hard metal body in at least one surface area. The multi-layer coating includes the following, sequentially in direction from the hard metal body to the surface of the cutting tool: at least one layer TiCN, where x+y=1, x&#x2267;0, y&#x3e;0; at least one layer TiCNO, where x+y+z=1, 0&#x2266;z&#x2266;0.03 and 0.5&#x2266;x&#x2266;0.85; at least one layer TiN, or TiCN, where 0.2&#x2266;x&#x2266;0.8 and x+y=1, or TiNB, where 0.0001&#x2266;v&#x2266;0.05 and y+v=1; at least one layer: TiNBO, where y+v+z=1 and 0.0001&#x2266;v&#x2266;0.05 and 0.01&#x2266;z&#x2266;0.6, or TiCNO, where x+y+z=1 and 0&#x2266;y&#x2266;0.5 and 0.01&#x2266;z&#x2266;0.6; and at least one outer layer &#x3ba;-AlO. The at least one layer TiCNOhas a texture in the direction having a texture coefficient TC=1.3.

Cutting tool for machining metallic materials

A coated article, in particular a tool for cutting machining, has at least one titanium diboride layer which has been deposited by a thermal CVD process and has a thickness of at least 0.1 &#x3bc;m. The titanium diboride layer has an extremely fine-grained microstructure with an average grain size of not more than 50 nm.
