Abstract (en)

[origin: EP2336423A2] The element (10) has a contact surface provided for attachment at a railway track (8) and designed as a friction minimizing sliding layer (22). The sliding layer is formed of cotton, hard rubber and/or plastic and/or metal and/or woven fabric. The sliding layer is formed at a surface of the element by halogenation and/or fluorination and/or flame impingement and/or plasma-and/or corona treatment. A low wear-layer (32) is made of plastic and/or woven fabric and/or polyurethane lacquer, and the sliding layer exhibits reduced roughness. An independent claim is also included for a method for manufacturing the damping element.
