Abstract
The present invention relates to a method for making a brake disc comprising the following operating steps: a) providing a brake disc, comprising a braking band 2 made of aluminum or aluminum alloy and provided with two opposite braking surfaces 2a, 2b, each of which at least partially defines one of the two main sides of the disc; b) depositing a material in particle form on the disc with HVOF (High Velocity Oxygen Fuel) technique or with HVAF (High Velocity Air Fuel) technique or with KM (Kinetic Metallization) technique, forming a protective coating 3 which covers at least one of the two braking surfaces of the braking band. The material in particle form is composed of 80 to 90% by weight of tungsten carbide, 8% to 12% by weight of cobalt and 2% to 6% by weight of chromium.
