Abstract
A method for making a brake disc may include the following steps: a) preparing a brake disc having a braking band provided with two opposite braking surfaces, (b) subjecting at least one of the braking surfaces to a working process adapted to increase the surface roughness thereof; c) nitrocarburizing the braking surface with increased surface roughness to obtain on the surface a nitrocarburized surface layer; (d) depositing on the nitrocarburized surface layer a material in particle form having: —Cr3C2 and NiCr, or —NiCr, Fe, Mo, Co, Mn and Al, which forms a base protective coating; and e) depositing on the base protective coating a material in particle form consisting of WC, Fe, Cr and Al, thus forming a surface protective coating of WC and Fe, Cr and Al.
