Brake disc for a friction brake of a transportation vehicle and method of manufacturing the same

A brake disc for a friction brake of a transportation vehicle, the brake disc comprising:

• a friction portion having at least one friction surface;
• a fastening portion for fastening to the transportation vehicle;
• a based body composed of gray cast iron or steel, wherein the friction portion and the fastening portion are formed on the base body of gray cast iron or steel;
• an anti-wear layer applied to the friction portion as the at least one friction surface, wherein the anti-wear layer is applied by laser deposition welding, wherein the anti-wear layer on the base body is applied beyond the friction surface into a region angled relative to the friction surface ending in that region, and wherein the anti-wear layer is applied in the angled region of the base body with full coverage without any gaps to the base body;
• and
• a contact plane at the friction surface between the anti-wear layer and a substrate thereof on the base body side, wherein the anti-wear layer continues into the angled region and seals the edge of that contact plane.
