If it should be a little harder than TiN
The titanium carbo-nitride layer indicates the following properties:
- Very high hardness
- High level of adhesion to substrate
- Relatively high thermal conductivity
- Low coefficient of friction against steel
- Cutting: Milling, turning, drilling and cutting tools for the processing of high-alloy and low-alloy steels with high feed and cutting speeds; very suitable for HSS mills in the area of steel machining.
- Froming: Drawing, stamping, pressing and forming tools for the processing of high-alloy and low-alloy steels and e.g. stainless steel sheets.
Like TiN, TiCN is also suitable for applications in plastic moulding and in the decorative sector!
In spite of its very high hardness, TiCN has not too high brittleness which is absolutely necessary for many applications, such as during interrupted cutting in machining. Frequently the application of TiCN layers results in a significant extension of lifetime with respect to TIN-coated tools.
The deposition of the TiCN layers take place by means of PVD technology. This allows the deposition of the layer on tool steels, HSS, cemented carbides or many other materials with T < 450° C.
Material: Titanium carbo-nitride, TiCN (multi-layers)
Microhardness HV 0.05: 3500 ± 500
