SILICUT – Aluminium Titanium Silicon Nitride

rivestimento-Silicut

Particularly hard coating, highly resistant to high heat development

Silicut is a nanostructured coating, made by incorporating Titanium and Aluminium Nitrides nanocrystals in a Silicon Nitride matrix.

The matrix forms a very thin film around AlTiN nanocrystals, works as a strong interface and provides the layer with the typical structure of composite materials.

The high percentage of aluminium in the layer allows the formation of a thermal barrier effective up to over 1100 °C.

.

Silicon, found in different percentages in the layer, leads to the formation of a ceramic coating with high hardness, a low coefficient of friction and very high resistance to abrasive wear. Silicut-coated tools maintain an excellent cutting performance.


When to use the Silicut coating



CARBIDE TOOLS FOR CHIP REMOVAL

Silicut has been developed for application on high performance chip removal tools made from carbide and steel which are used for high-speed finishing operations, including dry machining and machining of hardened materials up to 54-56 HRC.

GEAR TOOLS

Excellent for carbide hobs and stick blades for bevel gear cutting.

DRAWING AND DEFORMATION PUNCHES

High performance on steel and carbide punches for the drawing and the deformation of ferrous materials.
