The ideal coating for finishing various substrates.
Consisting mostly of carbon in the form of diamond and the rest in the form of graphite, black in colour, it has a substantially amorphous structure.

Its characteristics are very similar to those of the diamond.

    1. High hardness: up to over 3000 Hv.
    2. Low coefficient of friction: 0.05 – 0.2 which permits obtaining very high wear resistance and extremely constant sliding even at low speeds.
    3. Chemically inert, therefore very resistant to corrosion.
    4. Bioinert.
    5. Electrically insulating.
    6. Its special deposition process allows even extremely thin materials to be treated without deforming them.

7. It does not in any way alter the degree of finish of the surface on which it is applied, even on edges and corners.

8. Many types of metal substrates can be treated, including: steel, aluminium alloys, chrome, silicon, titanium.

9.Other metallic materials can be treated by applying a metallic interface layer.

10. Black colour.

11. Typical thickness of 2.5 (microns).


The possibility of treating titanium, together with its bio inertia, make it an ideal process for the production of parts for prostheses used in the orthopaedic field.

In the mechanical-textile field, it has made it possible to increase wear resistance due to the sliding of wefts on steel by up to 400%. At the same time, it has made it possible to reduce friction by 75% compared to chrome-only material.
Placed on tools for mechanical machining operations, on moulds or dies for extrusion, it produces a significant extension in the life span of the material.

Encouraging results have also been obtained on technical ceramic materials and in the field of optics.

The coating is carried out at low temperature, which also permits application on organic polymers including polyolefins and silicone-based polymers.
