FRICTION DISK HAVING AN ANTI-WEAR LAYER AND INTEGRATED WEAR INDICATION AND COMPOSITIONS OF THE ANTI-WEAR LAYER

摘要

A friction disc (2) with an anti-abrasion layer (1) and integrated wear indication, the friction disc (2) having a friction surface (2′) which is completely covered by the anti-abrasion layer (1). At least one indication surface element (3) which occupies a part of the friction surface (2′) and differs from at least one of the components friction surface (2′) and anti-abrasion layer (1) of the friction disc (2) in at least one of the features coloring and texture is provided between the anti-abrasion layer (1) and the friction disc (2). Compositions of the anti-abrasion layer (1) of the friction disc (2).
