A method for producing a brake disk for a wheel brake of a land vehicle includes laser depositing a duplex steel anti-corrosion layer to an axial friction side of a main body produced from gray cast iron at a surface speed of more than 10 m/min and applying an anti-abrasion layer to the anti-corrosion layer.

Brake disk and method for producing a brake disk

A process for producing a protective coating on a brake side of a brake disk main element includes using a laser powder build-up welding process. An NbC metal matrix powder or a CrCmetal matrix powder is produced by agglomeration and sintering of NbC particles or CrCparticles with particles of a metallic matrix composed of a stainless steel. During the laser powder build-up welding process, the NbC metal matrix powder or the CrCmetal matrix powder and an aluminum alloy powder is supplied simultaneously to a molten surface region of the brake disk main element which has been melted by a laser.

Process for producing a protective coating on a brake side of a brake disk main element and process for producing a brake disk

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.
