    摘要： A braking band (14) of a disc for a disc brake (100) suitable to rotate about a rotation axis (A-A), said braking band comprising opposite annular braking surfaces (16, 18) which extend from an inner edge (20) facing towards the rotation axis (A-A) to an outer edge (22) facing towards the outside of the disc, said braking band (14) having a distribution of grooves (44, 48, 52, 101, 103, 105, 107, 109, 111, 113) on at least one of the braking surfaces (16, 18), said distribution, or distribution assembly of grooves, having a pattern or module (42, 43) which is repeated circumferentially, each of said grooves (44, 48, 52, 101, 103, 105, 107, 109, 111, 113) being a closed groove which extends in a main direction of extension (46, 50, 54, 102, 104, 106, 108, 110, 112, 114) which defines a direction (46a, 50a, 54a, 102a, 104a, 106a, 108a, 110a, 112a, 114a) of said groove, each groove further extending without intersecting other grooves, said module (42, 43) extends from an inner radius (r1) to an outer radius (r2), said radii defining an annular portion of said braking surface having said grooves, said module (42, 43) comprising a first groove (44 and/or 105), which extends without interruption substantially from said inner radius (r1) to said outer radius (r2), as well as at least a second (48 and/or 107) and a third groove (52 and/or 109) with lesser extensions than said first groove (44), said first, second and third grooves (44, 48, 52 and/or 105, 107, 109) of the same module (42 or 43) have extensions parallel to one another, wherein said second groove (48 and/or 107) has a greater extension than said third groove (52 and/or 109), and wherein said at least first, second and third grooves (44, 48, 52 and/or 105, 107, 109) are positioned alongside one another and said second groove (48 and/or 107) is positioned between said first groove (44 and/or 105) and said third groove (52 and/or 109), and wherein the extension of said first groove is suitable to affect the entire area touched by at least one brake pad (124) suitable to act in conjunction with said annular braking surface (16 and/or 18) to exert a braking action, and wherein at any point in the direction of extension of each groove, said direction of extension (46a, 50a, 54a, 102a, 104a, 106a, 108a, 110a, 112a, 114a), or its rectilinear prolongation, forms an acute angle with respect to a radial direction (R-R) or a prolongation of the inner radius (r1) or of the outer radius (r2).

    摘要： A braking band having an annular band body arranged around a rotation axis and made of one of gray cast iron, steel, aluminum or alloys thereof, has at least one braking surface having an activated band body portion for increasing adhesive capacity of at least one protective surface coating placed on the surface of the activated band body portion and having at least one material with elevated resistance to abrasion. The activated band body portion is arranged on the surface of the annular band body to form an outermost layer of the braking band with the at least one protective surface coating and has a rough profile having at least one channel delimited by at least one pair of projections, extending along a path at least partially surrounding the rotation axis and having a channel bottom and a first channel side forming an acute angle with the channel bottom and an opposite second channel side forming an obtuse angle with the channel bottom.

    摘要： A method for making a brake disc may include providing a disc brake with a braking band and depositing on the disc a layer of chromium carbide and nickel-chromium in particle form to form a base protective coating. The method may also include depositing on the base protective coating a material in particle form consisting of tungsten carbide, iron, chromium and aluminium to form a surface protective coating made of tungsten carbide, iron, chromium and aluminium. Both protective coatings may be made by High Velocity Oxygen Fuel or High Velocity Air Fuel or Kinetic Metallization techniques.
