Abstract

The invention relates to a disc (1) for disc brakes, comprising a braking band (2), equipped with two opposing braking surfaces (2a, 2b), the braking band (2) being made of gray cast iron or steel, said disc comprising a base layer (30) covering at least one of the two braking surfaces (2a, 2b) of the braking band (2). Said base layer (30) consists of a matrix of titanium and/or a titanium alloy comprising one or more carbides and defines a tribologically active surface of the disc (1); or said base layer (30) consists of a layer of titanium and/or a titanium alloy and is in turn covered by a coating layer (300), which in turn consists of a layer based on one or more carbides and defines a tribologically active surface of the disc (1). Said one or more carbides are selected from the group consisting of titanium carbide (TiC), tungsten carbide (WC), chromium carbide, niobium carbide (NbC), molybdenum carbide (Mo2C), silicon carbide (SiC). At the interface between said base layer (30) and the braking band (2) in gray cast iron or steel there is an intermediate interfusion layer (32) having a mixed composition between said base layer (30) and the braking band (2), said base layer (30) having a crystalline structure with a growth direction predominantly orthogonal to the braking surface.
