Definitions
- the invention relates to a friction brake, in particular for motor vehicles such as road, rail and commercial vehicles, comprising a friction brake body, in particular a cast iron brake disc (1), whose friction surface (5) is provided with a wear layer (6) made of an iron alloy and which is applied to the friction surface (5) by thermal spraying or build-up welding, in particular by laser build-up welding, and which has predominantly iron (Fe) as the remaining component as an alloy component.
- a friction brake in particular for motor vehicles such as road, rail and commercial vehicles, comprising a friction brake body, in particular a cast iron brake disc (1), whose friction surface (5) is provided with a wear layer (6) made of an iron alloy and which is applied to the friction surface (5) by thermal spraying or build-up welding, in particular by laser build-up welding, and which has predominantly iron (Fe) as the remaining component as an alloy component.
- Wear layers of this type form the friction surface on brake discs of friction brake bodies on vehicles of the type mentioned.
- They advantageously consist of iron alloy compositions which, due to their high hardness and correspondingly improved abrasion resistance, are suitable as a wear protection coating for conventional brake discs made of steel or gray cast iron.
- the thickness of the brake disc as such can also be significantly reduced and the associated CO2 emissions can be reduced accordingly, both in relation to their production and during ongoing braking operation.
- WO2020/ 173756 A1 describes a brake disk with a wear-protection layer predominantly made of steel and with at least two elements selected from a group of nitride formers, namely chromium, molybdenum, vanadium and aluminum.
- the nitride formation creates a wear protection layer with high surface hardness which wear and especially abrasion on the frictional contact surface are reduced.
- the base body of the brake disc is a gray cast iron body, which is applied to the base body made of gray cast iron during production of the wear protection layer in two coating steps by thermal spraying and subsequent diffusion treatment with the aim of increasing the corrosion resistance on the one hand and the hardness of the coating on the other. Only through the diffusion treatment do the penetrating nitrogen atoms form nitrides with the proposed elements, which ensure the desired surface hardness.
- Other elements such as carbon and/or manganese should be present in the anti-wear layer at most as impurities.
- EP 3117025 Bl also relates to a wear protection layer made from an iron alloy on a brake disc made from gray cast iron.
- the essential alloy components consist of carbon to 0.5 to 2 wt. % , aluminum at 3-13 wt . % and optionally chromium at 0.5 to 5 wt . % .
- other alloying components such as Si, Mn, Ni, W, V, Nb and/or B can optionally be considered, with a residual proportion of iron and other traces of contamination typical of steel.
- the application of the protective layer is limited to the thermal spraying process, and the strength of the coating is also reduced because of the presence of aluminum Intermetallic brittle phases affecting the protective layer have to be accepted.
- DE 102019212844 A1 relates to a gray cast iron brake disc for land vehicles with an anti-corrosion layer, on which an anti-wear layer can be applied.
- This can be made of an iron-based alloy with a reinforcement of vanadium, niobium, boron or chromium carbide.
- the hardness of the reinforced iron-based alloy is limited to the carbide inclusions embedded in the soft ferritic matrix, which consists of a ductile mixed iron crystal.
- the present invention is based on the object of achieving a further improvement in the friction brake in terms of manufacturing complexity, wear resistance and long-term effectiveness.
- it is about the requirements for friction brakes of rail vehicles, where for reasons of cost, the Laser coating is used and long maintenance intervals are essential.
- Claims 2 to 5 are variants that relate to a selection of different alloying components that supplement the residual component iron, namely according to claim 2
- tungsten through tungsten carbide (WC) or carbon partly through the element boron with the carbon contained in the base material cast iron of the brake disc being dissolved out of the cast iron substrate in a controlled manner.
- tungsten through tungsten carbide (WC) or carbon partly through the element boron
- Addition of boron like vanadium, promotes the ductility of the alloy.
- a high proportion of carbon is to be desired in the melt, for example in order to obtain a particularly high hardness of the wear layer, then a high proportion of carbon will be selected in the powder/raw material mixture of the alloy components.
- Particular hardening agents such as the addition of alloying components of the elements vanadium (V), niobium (Nb), tungsten (W) and/or molybdenum (Mo) can improve the wear resistance of the coating, but compared to an alloy composition they are comprehensive of the elements Carbon, vanadium and chromium with the residual alloy component iron (Fe) more expensive.
- the wearing layer contains the alloy components
- V Vanadium (V) of at least 1.0% by weight
- the thickness of the brake disc accordingly, preferably taking into account a ratio between the layer thickness of the wear layer and the thickness of the coated substrate of the brake disc of around 1:5 to 1:7 to measure.
- a first braking system serves to brake the rotors.
- the brake for this braking system is located at the output of the rotors.
- the brake is used here to delay the rotor rotation at low speed of the brake disc with as little vibration as possible and to control the associated high level of fine dust pollution caused by the abrasion of organic brake material.
- the second braking system is intended for the generator drive.
- Brake discs with a relatively small diameter and for the brake calipers with sintered brake pads made of a brass alloy are suitable here, i. H . here we are dealing specifically with problems of abrasion (fine dust) and noise development.
- a particular advantage of the wear layer proposed according to the invention has been found on the test stand that compared to a bare, d. H . uncoated friction brake body made of gray cast iron, not only the desired reduction in wear values is achieved.
- the friction test also showed that the friction values of an uncoated gray cast iron brake disc, i.e. the desired braking effect, are achieved.
- the type of Application of the alloy components, which are preferably in powder form, must be observed by using suitable process methods.
- build-up welding and flame spraying are preferably considered, the latter in particular by using the known high-speed flame spraying process or by using the known atmospheric plasma spraying process, which processes are particularly suitable for ensuring permanent adhesion on a friction brake body structure that is preferably roughened on the surface and to realize a wear layer of high hardness with sufficient ductility.
- the laser application process and thermal powder plasma spraying are particularly suitable for iron alloy compositions applied as a powder, these processes being known per se and also ensuring a homogeneous quality of the finished anti-wear coating.
- the surface hardness that can be achieved is 2 to 3 times that of conventional gray cast iron brake discs.
- Fig. 1 shows a shaft brake disc in a three-dimensional representation
- Fig. 2 shows a half-section through a railway wheel with a brake disc and an enlarged detail A.
