The old-pink colored VARIANTIC® layer, abbrev. TiAlCN, represents a worthwhile alternative to the TiCN pure coating.
It indicates the following properties:
The deposition of the VARIANTIC® coating is performed by means of PVD technology. This allows the deposition of the coatings on tool steels, HSS, cemented carbides or many other materials with temperatures less than 450°C.
|Material:||Titanium-aluminum carbon nitride, TiAlCN (multi-layers)|
|Microhardness HV 0.05:||3500 ± 500|
|Coefficient of friction against steel 100Cr6:||0.2|
|Layer thickness [µm]:||2 – 4 |
|Maximum application temperature:||800° C / 1470° F|
|General characteristic:||Low friction, high oxidation resistance|
|Preferred applications:||For a large range of cemented carbides, Cermet and HSS tools; All steel grades in case of dry, semi-dry (MMS) as well as wet machining conditions; Excellent for the drilling of steel; drawing, stamping, pressing and forming tools for the machining of high-alloy and low-alloy steels|
 Dependent on tool size, for micro-tool also of less than 2 µm.
