Brake disc for disc brakes and method for making a brake disc for disc brakes

A method for making a brake disc, the method comprising the following operating steps:

• a) preparing a brake disc comprising a braking band equipped with two opposing braking surfaces, the braking band being made of gray cast iron or steel;
• b) depositing a first particulate composition comprising titanium or a titanium alloy on at least one of the two braking surfaces by a deposition technique using a laser beam, optionally the deposition technique using a laser beam being laser metal deposition (LMD), forming a base layer covering the at least one of the two braking surfaces of the braking band;
• wherein the method comprises forming on the at least one of the two braking surfaces a tribologically active coating layer comprising one or more carbides:
• including the one or more carbides in the first particulate composition to be deposited in step b), which in this case comprises titanium or a mixture of titanium and one or more titanium alloying metals, and the one or more carbides, in which case the tribologically active coating layer is constituted directly by the base layer,
• or
• depositing on the base layer in a step c) subsequent to step b) an additional layer based on the one or more carbides, in which case the first particulate composition to be deposited in step b) consists of titanium or a mixture of titanium and one or more titanium alloying metals, in which case the tribologically active coating layer is constituted by the additional layer, and wherein the 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), and silicon carbide (SiC).
