Definitions
- the invention relates to a multi-layer sliding bearing comprising at least a support body and a running layer and an intermediate layer disposed between the support body and the running layer, wherein the intermediate layer is formed of a nickel-free iron alloy containing at least one alloying element in addition to iron.
- Nickel is a metal commonly used in plain bearing technology as an alloying element in order to adapt the property profile of alloys. However, nickel is also used as a diffusion barrier layer between two layers of a multilayer plain bearing. As is known, nickel and its compounds are not safe for health.
- An intermediate layer has in principle the task of separating a base material, for example a bearing metal, from a surface layering.
- a base material for example a bearing metal
- the required properties and functions of the intermediate layer may differ.
- To simplify the Manufacturing processes should ideally cover an intermediate layer of several of the required properties and functions at the same time.
- one and the same intermediate layer can be used for a wide range of material pairings.
- the intermediate layer should in particular have at least one of the following properties, which are difficult to reconcile in an intermediate layer, or fulfill functions: diffusion barrier effect, adhesion promotion, low tendency to seize upon direct contact with the shaft or the mounted component.
- the intermediate layer is intended to have a high diffusion barrier effect against adjacent metals, in particular tin, zinc, aluminum and bismuth, but also media which penetrate a coating (eg oil components or water vapor, which penetrate a polymer coating relatively easily).
- a coating eg oil components or water vapor, which penetrate a polymer coating relatively easily.
- iron as the main alloying element.
- nickel with bismuth iron does not form intermetallic phases and the reactions with tin, zinc and aluminum are slower or at higher temperatures than nickel. It is the object of the invention to provide a nickel-free intermediate layer for a multilayer plain bearing.
- the object of the invention is achieved with the aforementioned multilayer sliding bearing, in which the iron alloy is formed X-ray amorphous or with crystal grains having a maximum grain size of 500 nm.
- the advantage here is that due to the small grain size of the alloy grains, the mechanical properties compared to conventional iron alloy interlayers can be improved because the network is reduced to possible weak points at the grain boundaries or a better distribution of these vulnerabilities can be achieved within the alloy. As a result, compared to an iron alloy of the same composition and coarser grains, the iron alloy has a higher elongation limit, a better tensile strength and a higher hardness and a higher elongation at break.
- the finer microstructure of the iron alloy has a positive effect on the use of the iron alloy as a diffusion barrier layer.
- An advantage of the invention is that the already very good diffusion barrier effect of iron as a main alloying element of the intermediate layer is improved by a particularly small particle size or even an amorphous deposition, since due to the higher number of grain layers or the absence of grain boundaries diffusion processes within the Shift slowed down.
- the smaller grains can also reduce the porosity when, for example, the iron alloy is deposited electrolytically, whereby its properties as a diffusion barrier layer can be further improved.
- some porosity of the intermediate layer may also have advantages in terms of adhesion-promoting properties. Extremely thin intermediate layers do not tend to completely cover the surface. Extremely hard and thus often brittle intermediate layers tend to form a fine crack network under mechanical stress or by internal stresses. In general, it is believed that these defects have a negative impact.
- iron alloys generally have a relatively high affinity and thus tendency to eat in contact with other iron materials (eg a steel shaft).
- other iron materials eg a steel shaft.
- the layer thickness of the intermediate layer is reduced, taking into account the diffusion barrier effect of the intermediate layer. Due to the improved properties of amorphous or nano-crystalline iron alloys, often much lower layer thicknesses are possible.
- the adhesive strength of other metallic layers applied to the iron alloy interlayer can be improved.
- the at least one alloying element is selected from a group comprising nitrogen, boron, phosphorus, sulfur, selenium, tellurium, ruthenium, chromium, manganese, tin, antimony, bismuth, silver, copper, zinc, molybdenum , Tungsten, aluminum, silicon, germanium.
- the diffusion barrier effect of the intermediate layer is further improved by particularly diffusion-inhibiting alloying elements.
- Each of the alloying elements carbon, nitrogen, boron, phosphorus, sulfur, selenium, tellurium, ruthenium, chromium, molybdenum and tungsten leads to a disruption of the crystal growth, an increased nucleation rate and thus to a grain size.
- a cubic-body-centered (ferritic) structure of the Fe phase also has a favorable effect on the diffusion barrier effect.
- This structure is facilitated by the ferrite-stabilizing alloying additions, in particular by at least one of a group consisting of or consisting of aluminum, phosphorus, chromium, manganese, molybdenum, ruthenium, tungsten.
- the diffusion barrier effect can be increased by reducing the concentration gradient of the diffusing metal.
- the diffusion of tin is reduced by using tin as the alloying element in the intermediate layer.
- tin as the alloying element in the intermediate layer.
- the adhesion of polymer-based surface coatings can be significantly improved by stable oxide films on the surface of the intermediate layer.
- the often high permeability of polymer-based layers requires relatively high corrosion and weathering resistance.
- Stable oxide films and high durability can preferably be achieved by at least one Alloy additives selected from a group comprising or consisting of aluminum, phosphorus, chromium, manganese, molybdenum, tungsten can be achieved.
- Limited interdiffusion can have a very favorable effect on the adhesion, in particular by the formation of strong metallic bonds and possibly also by an increased mechanical bond, which is mediated by protruding, by surface roughening interfacial increasing Intermetallic phases.
- Reactive alloying elements selected from a group comprising or consisting of copper, manganese and zinc have a particularly favorable effect here. An enrichment of these elements near the interfaces, ie in particular the formation of a concentration gradient with increasing concentration in the direction of the interface, can further improve these positive properties.
- the scavenging tendency over other iron materials compared to unalloyed iron can be significantly improved by intermetallic phases formed become.
- Stable oxide layers of iron also mixed oxides with iron
- oil additives e.g., friction modifiers
- Alloy additions of one or more elements of the group copper, manganese, and zinc can also reduce scavenging, presumably by the formation of lubricious sulfides in combination with oil additives (e.g., EP additives).
- oil additives e.g., EP additives
- the affinity in comparison to steel can be reduced so much that a coating of the bearing backing which is unavoidable, for example, in the course of the electrodeposition is deliberately carried out in a higher layer thickness, in particular with a layer thickness selected from a range of 2 ⁇ m to 30 ⁇ m to additionally improve the resistance of the steel back to fretting.
- a total content of the alloying elements in the iron alloy is between 2 at.% And 49 at.%, In particular between 10 at.% And 30 at.%. The remainder to 100 at.% Is formed by iron.
- iron is still present as a separate phase and not mainly intermetallic phases in the intermediate layer are present, or that especially in amorphous or extremely fine crystalline layers (in which a distinction of phases by X-ray diffractometry is not possible), the positive Properties of iron (diffusion inhibition, formation of oxide layers, etc.) are sufficiently preserved.
- the iron alloy is austenite-free.
- the iron alloy preferably has a ferritic structure.
- ferrite has a less dense packing of the atoms than austenite in comparison to austenite due to its cubic body-centered lattice and is more susceptible to corrosion, the ferritic microstructure achieves better adaptability to the further layer associated therewith and better bondability to this layer, as a result of which the adhesive bond the further layer can be improved with the intermediate layer of the iron alloy.
- the iron alloy can have a hardness of between 400 HV (1 ⁇ 10 -3 N) and 1000 HV (1 ⁇ 10 -3 N). Due to this high hardness of the intermediate layer, it is possible to make this much thinner than is the case with conventional intermediate layers of iron or iron alloys.
- the crystal grains have a substantially round habit and / or at least 90%, based on the total number of crystal grains, are aligned with at least one crystallographic axis at least approximately parallel to the surface. On the one hand, this reduces or avoids a possible notch effect of the crystal grains. On the other hand, it can thus by the preferred orientation an improvement of the effect as a diffusion barrier layer can be improved by providing a denser structure on the surface of the intermediate layer.
- the particles are embedded.
- the particles preferably have a mean diameter between 0.1 ⁇ m and 1 ⁇ m and / or are present in a proportion of between 3% and 30% by volume, based on the total intermediate layer.
