also known to harden for the wear-resistant coating. The new process offers the advantage that alloys that are bare and deformable always have to be used. The friction disks produced in this way contain copper and possibly also lead. have a constant friction coefficient in continuous operation. These alloys have no cracks when combined, they show no cracks and also have good sliding properties as a material - thin lamellae are inexpensive to produce in series production without shafts, high wear resistance and high noticeable failures.
