Hard Coating Series

Si-doped Coatings

The Si⁺-coating was developed for machining of hardened and highly alloyed steels as well as alloys with a high hardness (over 60 HRC). This coating shows an excellent wear resistance as well as excellent thermal stability. As a consequence the Si⁺-coating permits extreme cutting conditions at highest temperatures of over 1,100°C.

Due to the multilayered composition the Si⁺-coating provides a double function as the ductile base coating already shows a high wear resistance and hot hardness but can be increased considerably through the Si-containing top coating.
