Definitions
- the invention relates to a wear protection-coated component made of a steel alloy, in particular a component of a fuel injection system, the tribologically stressed surface of which is at least partially coated by a plasma process with a hard outer wear protection layer that is applied to a metallic adhesive layer.
- the field of application of the invention extends primarily to motor vehicle technology, in particular to fuel injection systems.
- Their components which are usually made of high-alloy steel, such as valve seats of fuel injectors, sliding bearing points in high-pressure pumps and the like, are exposed to strong pressures and frictional loads during operation, so that surfaces of the components of interest here that are subject to high tribological stress are usually provided with a hard wear protection layer, which in particular significantly reduce the coefficient of friction in tribological contacts.
- Such wear protection layers contain, for example, chromium nitride, titanium nitride or DLC (diamond-like carbon).
- these wear protection layers can also be used in connection with other components, for example in tool technology and to that extent as tool coatings.
- PVD Physical Vapor Deposition
- an additional adhesive layer made of a material with good adhesion properties - for example chrome - is usually used as an intermediate layer, which is usually arranged directly on the surface of the steel component, i.e. between it and the hard wear protection layer.
- the wear protection layer arrangement has an outer wear protection layer formed from tetrahedral amorphous carbon or having a proportion of tetrahedrally bound amorphous carbon, as well as an adhesive layer between the surface of the component and the wear protection layer.
- the adhesive layer provided as an intermediate layer consists essentially of titanium and also has at least one oxidation-resistant element. This reduces the high chemical reactivity of titanium and increases the resistance to oxidation in the adhesive layer, which benefits the durability of the entire wear protection arrangement.
- the adhesive layer is also applied here using the PVD process.
- a component to be coated consists of a high-alloy, hardened, surface-carburized or nitrided steel
- additional material phases are formed by diffusion processes at the interface between the steel and the adhesive layer during PVD coating or during component operation, which lead to so-called delamination .
- the unwanted diffusion process is triggered by a difference in concentration of the individual elements at the interface between the steel material of the component and the adhesive layer.
- a additional intermediate layer for example, titanium from the intermediate layer combines here with carbon from the steel material of the component to form titanium carbide.
- This additional intermediate layer is therefore not applied in a targeted manner, but is created by the diffusion process of the alloying elements or carbon or nitrogen from hardening processes of the steel material of the component at the interface with the adhesive layer. This results in the problem of crack formation in the additional intermediate layer, which in extreme cases can ultimately lead to the aforementioned delamination.
- the invention includes the technical teaching that in the case of a wear protection coated component made of a steel alloy, the tribologically stressed surface of which is coated with a hard outer wear protection layer which is applied to a metallic adhesive layer.
- Fe iron
- the surface of the component acting as a diffusion front is separated from the adhesive layer and there is therefore no risk of delamination.
- the additional iron layer acts as a diffusion buffer and absorbs the alloying elements of the steel material of the component, so that the interface between the iron and the adhesive layer is protected from the formation of additional material phases.
- the metallic adhesive layer is bonded to the previously applied Fe buffer layer of the component, so that the concentration gradient of the diffusion of alloying elements from the steel material is present at the transition between the same and the Fe buffer layer, and not to the adhesive layer.
- the Fe buffer layer is chosen so thick that the diffusion front always remains in the Fe buffer layer over the entire service life of the component. This can be ensured with a layer thickness between preferably 0.01 and 50 ⁇ m for the Fe buffer layer, depending on the component material and application.
- the high-alloy, hardened or nitrided steel is a material that is selected from a steel group comprising chromium steels, chromium-molybdenum steels, chromium-vanadium steels, chromium-molybdenum steels Vanadium steels.
- the wear-resistant coated component can consist of nitrided X40CrMoV5-1, which can be used for components of a fuel injector or the like.
- the outer wear protection layer preferably consists of a tetrahedral, hydrogen-free amorphous carbon layer (Ta-C).
- Ti-C tetrahedral, hydrogen-free amorphous carbon layer
- CVD Chemical Vapor Deposition
- the metallic adhesive layer preferably consists of high-purity chromium, titanium, tungsten and / or molybdenum. A mixture of titanium-aluminum or the like is also conceivable.
- the adhesive layer increases the resistance of the hard wear protection layer and can also be applied automatically by plasma coating in a vacuum coating machine, which for this purpose deposits the adhesive layer element.
- the adhesive layer can also be applied in multiple layers.
- FIG. 1 shows a schematic longitudinal section through a wear-resistant coated component according to the invention of the earth
- FIG. 2 shows a flow chart of the method steps for coating the component according to FIG. 1.
- a component 1 - shown here only schematically - consists of a hardened, high-alloy chromium-molybdenum steel.
- the hardening process results in carbon in the material structure.
- the component 1 is provided with a hard outer wear protection layer 2, which is designed as a generally known tetrahedral hydrogen-free amorphous carbon layer and to that extent forms a protection for the tribologically stressed surface of the component 1.
- the hard outer wear protection layer 2 is applied to a metallic adhesive layer 3 made of high-purity chromium.
- This metallic adhesive layer 3 is in turn applied to an Fe buffer layer 4 which is applied to the surface of the component 1.
- the surface of the component 1 acting as a diffusion front is separated from the adhesive layer 3 by the Fe buffer layer 4 in order to prevent delamination.
- the carbon from the steel alloy of the component 1 cannot combine with the chromium from the adhesive layer 3 to form chromium carbide, which results in an additional material phase which would lead to delamination as a result of crack formation. Instead, the diffusion process takes place entirely in the Fe buffer layer 4, so that alloying elements of the component 1 cannot penetrate as far as the adhesive layer 3.
- a component 1 is coated with the wear protection resistant according to the invention by initially providing a component 1 made of a steel alloy in a step A. Subsequently, in a step B, an Fe buffer layer 4 is deposited on the surface of the component 1 using a plasma process. Subsequently, in a step C, a metallic adhesive layer 3 is applied to the Fe buffer layer 4 by means of a plasma process. Finally, in a step D, the outer hard wear protection layer 2 is applied to the metallic adhesive layer 3 by means of a plasma process.
- the application of the Fe buffer layer 4, the metallic adhesive layer 3 and the hard wear protection layer 2 takes place in this embodiment by deposition using the PVD process as a plasma process, specifically by vacuum arc evaporation, in the same PVD machine after the component 1 has been provided in a cleaned state is.
- the invention is not limited to the preferred exemplary embodiment described above. Rather, modifications thereof are also conceivable, which are also covered by the scope of protection of the following claims.
- a vacuum arc evaporator it is also possible to use a different plasma coating method for applying the layer structure to the surface of the component.
- This can also consist of another high-alloy steel of the steel groups specified above, which is hardened, carburized or nitrided in order to achieve a high component strength for a tribological load which preferably occurs in the context of a fuel injection system.
