Abstract: It is disclosed and induction furnace (1) comprising: a box-like housing structure (2, 6), which defines an internal chamber (3) of the induction furnace (1); an infiltration crucible (7) housed in the internal chamber (3) and comprising a first (10) and second (11) essentially mutually parallel and spaced away radiation plates, made of susceptor material, and an infiltration chamber (13), which is interposed between the radiation plates (10, 11) in order to be heated by the plates, the infiltration chamber being provided for housing a semifinished workpiece (14), to be subjected to infiltration, and infiltration material (15); at least an induction coil (L1, L2) housed in the internal chamber (3) to be supplied with at least an electrical current (i1, i2) for induction heating of the radiation plates (10, 11).

Abstract: A method for making a composite structure or a portion of a composite structure of a braking band of a brake disc, unusually capable of obtaining a structure with an especially long life, comprising at least the following steps: making a composite ceramic structure, comprising carbon fibre filaments, silicon and silicon carbides, obtaining a body of a braking band comprising at least one braking surface; processing said braking surface removing a surface layer so as to have carbon not bonded with the silicon on surface; removing at least partly the carbon not bonded with silicon from the surface; depositing an anchoring substrate on said braking surface; and depositing a protective coating on said anchoring substrate.
