Black Hard Coating on Captive Bezel
High quality coating - only in combination with TEGIMENT
Schematic structure of our hard coating on a surface hardened using TEGIMENT Technology. We only use hard coating (PVD coatings) with TEGIMENT surfaces. Because only in this combination is it possible for our PVD paint coats to achieve their required high quality.
The hardness profile of the TEGIMENT layer is continuous, i.e. the high hardness of the surface transitions very gradually to the basic hardness of the material itself. This makes it possible to apply a PVD coating without any risk of the otherwise familiar peeling effect from the body of the case.
Paint coatings applied using the PVD technique are exceptionally hard. They have a hardness level of up to 2,000 Vickers. The great and sudden difference in hardness between the hard coating and the base material results in disruption between the two when subjected to stress because the hard shell (PVD coating) is applied with no transition to a very soft core (case material). If a local force is applied, the base material yields and cannot provide sufficient support for the outer layer. This is called the "egg shell effect".
The hardness of the TEGIMENT surface, by contrast, supports the hard coating layer. This
Thanks for this, O. I must have missed it. Impressive what Sinn has done.
