The double-layer coating TN2, manufactured with a dropless method and treated with the surface fine finish
processes, features very good resistance to abrasion, high thermal resistance and low coefficient of friction.
Due to reduction of friction, the tool’s life is considerably longer, and the quality of the surface processed by
the tool is improved. By combining the extremely hard TiAlN layer with the malleable TiN layer, we have obtained
a smart, self-adjusting structure of the tool's surface, which accommodates itself to the processing related stresses,
thus improving the tool's resistance to breaks. Tn2 is intended, in particular, for the tools for processing of the Group
P materials (for Rm < 1000 MPa), and the materials from Groups M, K, N.
TC COATING

Coating TiN + TiCN

Structure Multilayer

Hardness 3700 HV 0,05

Max. working temp 400°C

Coefficient of friction 0,2

Anthracite

Color of coating

TC is a multilayer, general purpose coating. It features a very high hardness, good durability and low coefficient
of friction. The basic TiN layer provides high adhesion to a tool and considerable resistance to dynamic loads.
The top TiCN/TiC layer, with its high hardness and low coefficient of friction, ensures a very good resistance to
abrasion. Combination of the above properties allows for protection of the edges from the processed material
buildup, and from chipping. Due to the relatively low temperature resistance, proper cooling of the tool should
be applied. The coating is intended mainly for the tools for processing of materials from the Groups P (in particular
of high strength Rm > 1000 MPa) K, N, H.
