- a first embodiment of the invention relates to a friction disc as it is used as a disc brake disc or as a clutch disc, which is equipped to minimize wear and thus the formation of fine dust with a wear protection layer on the friction surface of the friction disc. Since the interaction of friction lining and friction disc represent a special friction system, an indication of the life of the wear protection layer or an indication of the exceeding of the life of the protective layer on the friction surface is of particular importance. Between the wear protection layer, which covers the friction surface over the entire surface and the friction disc, one or more indication surface elements are provided, which occupy part of the friction surface and clearly differ in coloration and / or structure from the friction surface and / or the wear protection layer.
- buttons can be arranged distributed over the friction surface at a distance from one another, but the formation of an indication surface element as a ring-like circumferential structure is also conceivable.
- With the help of between wear protection layer and the friction surface of the friction disc arranged indicator surface elements can be accurately recognized when a critical wear of the protective layer has occurred and therefore a change of the friction plate is necessary. If the protective layer worn, there is a change in the coefficient of friction, which has an effect on the interaction of the friction lining and the friction plate, which leads to an increase in wear of the friction plate and an increase in fine dust formation.
- the indication surface element arranged under the wear protection layer is exposed as soon as the wear protection layer has been removed to the specified depth. Since the indication surface element can also protrude into the wear protection layer, are
- the indication of the critical wear takes place in particular by visually recognizable indication surface elements.

- the indication surface element lies under the wear protection layer and becomes visible only after the critical wear.
- it consists of a colored, black zen or white ceramic, a mineral dye and / or a fiber fabric or braid.
- metal or ceramic foams are suitable.

- ceramic hard particles which consist in particular of aluminum oxide (corundum) and / or titanium dioxide may be embedded in the wear protection layer.
- compositions of the wear protection layer of a friction disk according to the invention relate to compositions of the wear protection layer of a friction disk according to the invention, depending on whether it is a metal alloy, a cermet or a ceramic.
- the composition may consist of a chromium- and / or nickel-containing tungsten-based alloy or a chromium-nickel steel.
- the tungsten base alloy is a composition preferably containing 20 to 35% by weight of chromium and 5 to 15% by weight of nickel, and more preferably 27% by weight and 10% by weight of nickel having a content of 100% by weight. -% balancing residual content of tungsten and the usual alloy traces of contamination has.
- the alternative chromium / nickel steel has in a preferred embodiment at least 16 wt .-% chromium and at least 10 wt .-% nickel, more preferably a chromium content of 16.5 to 20 wt .-% and a nickel content of 10 to 26% by weight.
- a cermet is used for the wear-resistant layer, then this can be composed of a tungsten alloy in which ceramic particles of Al 2 O 3 , TiO 2 and / or SiC are contained.
- An alternative cermet is present with WC and / or CrC in a metallic matrix of Ni, Co and / or Cr, wherein a proportion of WC of 60 to 85 wt .-% is particularly preferred.
- Particularly suitable is a cermet with 70 to 85 wt .-% WC and 7 to 12 wt .-% Co ..

- Fig. 2a is a plan view of a friction surface cutout with two different
- Fig. 2b is a side sectional view corresponding to the view of Fig. 2a.
- the friction disc according to the invention relates primarily to brake discs, but other friction discs such as clutch discs are also included.
- the brake disks may be a composite brake disk or a brake disk made of solid material, which according to the invention is provided with a wear protection layer on the friction surface which is present on the friction ring of the friction disk and comprises an integrated wear indication.
- Fig. 1 shows an internally ventilated brake disc 2, which may be made of a gray cast iron, steel or an aluminum alloy.
- a wear protection layer 1 is applied in each case, which has a thickness of less than 200 ⁇ , preferably of less than 50 pm.
- an indication surface element 3 a locally applied layer of an indicator material can be seen in FIG. 1, which is surrounded by the wear protection layer 1.
- This indicator surface element 3 is optically detectable when the wear protection layer 1 is correspondingly worn or worn out.
- at least one further indication surface element is arranged on the second friction surface, which, however, is then not directly visible from the outside when the
- Brake disc is mounted on a vehicle.
- Two different embodiments of an indicator surface element 3 are shown in FIGS. 2 a and 2 b, both initially being a depression 3 introduced into the friction surface 2 'of the friction disk 2. While the indication surface element 3 shown on the right side is merely realized by countersinking, so that after wear of the protective layer 1, as shown in FIG. 2a, only the contour becomes visible, for example as a blind hole, the depression is on the left side with an indication material 3, which differs in terms of color and / or structure of the friction surface 2 '. On the one hand, color differences can be achieved by using white, black or colored materials as the indicator material, but it is also possible to cause discoloration by a chemical, in particular oxidative, reaction as a result of the heat action of the friction system.
- indicator materials for example, ceramics in question, which may have a white color of Al 2 0 3 or Ti0 2 or a black color of SiC. Other colors can be realized by mineral colors such as metal oxides.
- the ceramic can be used as an inlay in a depression or placed on the friction surface before the wear protection layer is applied. The attachment can be done by suitable bonding or possibly. Welding or soldering.
- the indicator element is poured during casting of the friction disc.
- a white ceramic can be used as indicator material, which is first sprayed into the indicator recess during production of the coating of the coating, for example, whereupon the wear protection layer is then sprayed on by switching the sprayer to the metal / ceramic coating.
- Structural differences to the optical detection of the indication surface element may be implemented by, for example, a metal fiber mesh or metal mesh insert, for example by pouring a small steel tissue into an aluminum brake disc. In this way, advantageously metal or ceramic foams can be implemented.
- Wear protection layer has exceeded its service life and removed or

All geometric figures and design elements are conceivable, indication surface elements can also be triangular, star-shaped or formed approximately from letters. If the surface element is designed as a ring-like circumferential structure, then this may also be a circular ring or represent a curved or serrated band.
- the revolving structure is particularly easy to recognize, as it may not, as locally applied elements may be obscured by the rim mounted in front of the brake disc. Thus, with a revolving indication surface element, it can be seen at first glance, even when the wheels are mounted, whether the brake disk has to be replaced or not.
