The present invention concerns the field of vehicle technology and industrial-plant technology and relates to a brake disc provided with protection from wear and corrosion and to a method for production thereof. The known solutions have the disadvantage that the coating for providing protection from corrosion and wear is applied to the frictional surfaces of the brake disc and is rubbed off straight away during the first braking operations. The present invention addresses the problem of providing a brake disc that has improved and durable protection from corrosion and wear. The significantly improved properties of the brake disc in terms of protection from corrosion and wear are achieved according to the invention by at least the region of the frictional surfaces (2) having an AlSi-based diffusion layer (3), which has a layer thickness of 0.1 mm to 0.6 mm and is formed in the process of interaction with the steel or grey cast iron of the metal main body (1). The brake disc according to the invention can be used for example in vehicles or as a braking system for industrial brakes or in wind turbines.

A method is disclosed for producing a friction brake body, in particular a brake disc, which has a main part with a frictional contact region. A wear protection layer is produced on the frictional contact region by way of laser cladding using a laser beam oriented towards the frictional contact region. The wear protection layer is produced by at least one pulverulent additive during the laser cladding. At least two pulverulent additives are added simultaneously such that the dwell time thereof in the laser beam differs.

A friction brake body, in particular a brake disc, for a friction brake of a motor vehicle is disclosed. The friction brake body has a main part with at least one wear protection layer on at least one frictional contact region of the main part. The wear protection layer forms a frictional contact surface on the wear protection layer face facing away from the main part. The degree of hardness of the wear protection layer increases incrementally or continuously from the main part to the frictional contact surface.

Systems, devices, and methods are provided for manufacturing a carbon ceramic brake disc. Generally, a plurality of uncured or partially-cured bulk molding compound preforms or molding compound layers and ventilation cores are placed in a mold cavity and warm-pressed at a first temperature. The ventilation cores are removed from the resulting cured green body. The cured green body is then removed from the mold, and treated through a polymer infiltration and pyrolysis or reactive melt infiltration process. Certain steps can be repeated until a desired target density or weight is attained.

A braking band having an annular band body arranged around a rotation axis and made of one of gray cast iron, steel, aluminum or alloys thereof, has at least one braking surface having an activated band body portion for increasing adhesive capacity of at least one protective surface coating placed on the surface of the activated band body portion and having at least one material with elevated resistance to abrasion. The activated band body portion is arranged on the surface of the annular band body to form an outermost layer of the braking band with the at least one protective surface coating and has a rough profile having at least one channel delimited by at least one pair of projections, extending along a path at least partially surrounding the rotation axis and having a channel bottom and a first channel side forming an acute angle with the channel bottom and an opposite second channel side forming an obtuse angle with the channel bottom.

A brake element for a transportation vehicle, having a base body that is planar at least in some regions, to the planar sides of which at least two build-up layers are applied in each case at least in some regions. The build-up layers form a surface which, in the mounted state of the brake element on the transportation vehicle, serves as a friction surface for a brake pad. There is a bonding zone in which both a material of the base body and a material of a build-up layer adjacent to the base body are present, wherein the bonding zone has a thickness perpendicular to an areal extent of a planar side that is less than 10 μm.

In some implementations of the current subject matter, a brake rotor can include a supporting layer applied to a friction surface of a brake rotor substrate, which can optionally include cast iron, and a coating applied over the supporting layer. The supporting layer can include a preparatory metal, and the coating can impart wear and corrosion resistant properties to the friction surface. Related systems, methods, articles of manufacture, and the like are disclosed.

In various embodiments, the oxidation protection system comprises a boron-glass layer formed on the composite substrate and a silicon-glass layer formed over the boron-glass layer. Each of the boron-glass layer and the silicon-glass layer includes a glass former.

An oxidation protection system disposed on a substrate is provided, which may comprise a boron layer comprising a boron compound disposed on the substrate; a silicon layer comprising a silicon compound disposed on the boron layer; and at least one sealing layer comprising monoaluminum phosphate and phosphoric acid disposed on the silicon layer.
