Abstract
A method for making a braking band of a cast iron brake disc with increased resistance to wear and corrosion, may have the following steps: a) making a braking band of a brake disc of cast iron, preferably gray cast iron; b) immersing at least partially the braking band in molten aluminum maintained at a predetermined temperature so that the molten aluminum covers at least a predetermined surface region of the braking band. Forming intermetallic iron-aluminum compounds at a surface layer of the braking band and generating a layer having of intermetallic iron-aluminum compounds in the predetermined surface region of the braking band. The method may also have the steps of c) extracting the braking band from the molten aluminum; and d) removing the aluminum remaining adherent on the braking band after extraction to expose the layer of intermetallic iron-aluminum compounds on the surface.
