Low friction coating

Argor-Aljba, already equipped with arc PVD deposition technologies, filtered arc PVD (patented), PVD sputtering and PACVD, has recently introduced a new coating technology that integrates PACVD with HiPIMS.

This integration, developed in collaboration with Hauzer technicians on Argor-Aljba specifications, allows us to expand the proposal range of coatings, to increase flexibility in production and to offer customers a product with higher wear resistance. Contact us for more information.

Argor-Aljba has increased the range of ta-C DLC coatings by introducing the "Argor Tool" family, specially developed to offer its customers an advantageous price/performance ratio. The coatings belonging to the Argor-Tool family, called dialong®-R, dialong®-G, dialong®-T, are deposited with the arc PVD technology patented by Argor-Aljba and are mainly dedicated to the sector of tools for processing non-ferrous materials.

It is estimated that 20% of all energy produced is used to overcome friction, mainly in industry and transport. The interaction between two surfaces generates friction which causes loss of energy and can also damage the surface itself. Lubricating oils help to decrease the friction coefficient but represent an environmental risk in their own right. A low friction PVD coating, especially a diamond-like carbon coating (DLC), is an excellent solution.

1. Extreme scratch resistance

Nobody wants scratches on their watch. Protects both the glass and on the case. Stainless steel and titanium can be prone to scratches when exposed to other harder metals. The harder the material used for the case, the more scratch-resistant the watch will be. For this reason, watch components coated with Dianoir® are extremely hard and therefore more resistant to scratches than other PVD coatings.

2. High resistance to abrasion and wear

Watch cases coated with Dianoir® have a longer service life. Thanks to the hardness of the DLC coating, accidental intrusion of hard particles or damage is almost impossible. The dial and movement components (which can also be coated with Dianoir®) are also protected by the robustness of the DLC.

3. Comfortable fit

The smooth surface of the Dianoir® coating ensures a comfortable feel on the wrist. The smoothness of the casing is also felt on the skin and is enhanced by the Dianoir® coating.

4. Excellent biocompatibility

In addition to its good mechanical properties, Dianoir® is 100% biocompatible. Dianoir® coatings do not contain any allergenic metals and also serve as protection against nickel content.

5. Exceptional heat resistance

Cover coatings Dianoir®, Dianoir®G2, Dianoir®G3 and Dianoir®G4 optimise the high temperature resistance (up to 500°C) of stainless steel and titanium cases.

6. Unique aesthetics

In addition to its exceptional protective qualities, each watch with Dianoir® coatings is distinguished by its particularly elegant and classy appearance. For a deep black finish, choose Dianoir®G2 suitable for every occasion and every style of dress. The perfect combination of sophisticated technology and aesthetics.
