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.

At least one coated valve seat region has at least one first layer and a second layer, the second layer is arranged on the first layer, and the first layer and the second layer are different. The first layer and the second layer are each formed by a local thermal deposition welding method. In the case of a cylinder head of an internal combustion engine, a valve seat region is formed by depositing a first layer on a substrate material of the valve seat by a laser deposition welding method in one method step and, in a subsequent method step, depositing a second layer on the first layer by a laser deposition welding method. The second layer contains a material which exerts a material hardening effect.
