Abstract

A brake disc for disc brake comprises a braking band made of gray cast iron or steel, provided with two opposite braking surfaces, each of which defines at least partially one of the two main faces of the disc. The brake disc is provided with a base layer totally nickel-free and one or more carbides included in the nickel-free steel, which covers at least one of the two braking surfaces of the braking band. An intermediate layer composed of nickel-free steel is interposed between the base layer and at least one of the two braking surfaces of the braking band.
