Abstract
A brake disk for a wheel brake of a land vehicle includes a main body formed from gray cast iron. The main body has at least one axial friction side, at least one anti-corrosion layer applied to the axial friction side, and at least one anti-abrasion layer applied to the anti-corrosion layer. The anti-corrosion layer is a duplex steel layer that provides a cost-effective coating for the brake disk and enables improved corrosion resistance. The anti-abrasion layer is wear resistant and is provided by a SiC material containing at least one oxidic or metallic binder, or by an iron-based alloy having a vanadium carbide reinforcement, a niobium carbide reinforcement, a boron carbide reinforcement, a chromium carbide reinforcement or combinations thereof.
