Manufacturing

ROCATRON has a manufacturing strategy for producing the hard coating either at HS-Technik in Siegendorf or at selected manufacturing partners. The choice of laser power and the associated coating strategy depends on the application and the layer system (double or mono layer). The final processing of the brake disc is carried out by turning (mono layer) or by grinding (mono and double layer) or by honing (mono and double layer).

The technical Solution

The ROCATRON hard coating (EURO 7) can be designed in two versions.

Double Layer

With the double layer, the well-known layer system with an adhesive and carbide layer is applied to the friction surface of the brake disc. The materials used for the ROCATRON Double Layer are based exclusively on our own developments.

Monolayer

The ROCATRON monolayer is a design patented by ROCATRON. The ROCATRON Monolayer is a compromise between a double layer coating and a brake disc made out of a more wear-resistant base.

The Practice

As soon as a conventional brake disc is replaced by a brake disc with a hard coating, the time the brake disc remains in the vehicle can be extended by years. Therefore, measures must be taken to ensure that environmental influences do not damage the brake disc. ROCATRON solves this problem with the combination:

Hard coating  + Long-term corrosion protection = ROC+

The associated process steps are:

Coating of the friction surface
