Summary of the invention
The object of the present invention is to provide a kind of sliding bearing, this sliding bearing also has the good embeddability to foreign matter when sliding layer has good wear resistance; And provide a kind of method that is used for making this sliding bearing.
The method that described purpose is mentioned by beginning on the one hand is achieved; described layer is made by at least two kinds of mutually different materials in the method; wherein; one of material only is injected in the zone that substrate limits in first step; wherein; the zone of not using this material coating of substrate surface prevents deposition of material by veil protection; and at least one second step, be other zone-coating with at least a material in the other material by spraying; and described purpose is achieved by a kind of sliding bearing; two of sliding layer zones are by the material powder manufacturing that applies by means of injection method in this sliding bearing; wherein; different materials borderline region in form to connect; perhaps be achieved by following sliding bearing, the material for sliding bearing of first area by metal consists of and second area consists of by anti-friction lacquer in this sliding bearing.
At this advantageously, by using veil or template, so that cover thus substrate need not the first material coating zone, i.e. sliding bearing halfliner for example, the possibility that provides now is, bi-material or all material of structure sliding layer directly contact with same base, be used for no longer needing to consider that this is to be achieved because of the layer that is under this substrate of this adhesion strength by substrate or sliding bearing aspect the material adhesion strength each other of sliding layer thus.Can adopt thus disabled for the sliding bearing layer, especially for the combination of the material of sliding layer up to now, thereby can make such sliding bearing, this sliding bearing is realized the purpose of conflicting better, namely, realize embeddability and adaptation ability on the one hand, and realize on the other hand bearing capacity or wear resistance.Improve Economy for the manufacture of described sliding bearing by injection method in addition, particularly in making the corresponding layer of sliding bearing, designed thus the application of different materials also more economically.Being used for generating the zone that the material by different of sliding layer consists of-these materials by the material that adopts powder type is by means of the favourable part that injection method applies-realizes on the one hand, based on the particle form of powder can for target finish coating to substrate, namely, avoid material " extension " in adjacent layer region, wherein, the favourable part that realizes on the other hand is, by producing connection physics or machinery between each material in this borderline region between each material of injection method, can improve thus the cohesiveencess of sliding layer.Also possiblely but then be, by multiple material consist of the layer a zone consist of by anti-friction lacquer, can simpler and more save thus instrument ground and implement the ensuing particularly processing of machinery, thereby can simpler and more advantageously get rid of the holiday that exists in case of necessity, these holidaies are for example possible, and coating material produces owing to crossing in large area.The advantage that adopts in addition anti-friction lacquer also to have is, can apply with relatively low temperature this anti-friction lacquer, thereby can avoid thermal force and the thus phase transformation in metal layer in the part layer that has applied of the layer that is consisted of by multiple material, thereby can limit in advance better desired characteristic profile.The advantage that adopts in addition anti-friction lacquer also to have is, can be not yet to substrate carry out may situation under needed pretreatment and directly apply this anti-friction lacquer and realize in addition with layer enough strong connections of adjacent alloyed region.This material can prevent in addition the prematurely so degree ground wearing and tearing of one of material by structure connection in the borderline region between each zone that is consisted of by different materials, so that namely can lose in the remaining working life of sliding bearing.
Set according to a kind of enforcement flexible program according to the present invention, be coated in temporary transient whole the ground of described at least a other material in the substrate and then by reprocessing to make the first material to expose to the machinery of layer.Compensating coating defective better thus, these holidaies may not occur when for example absolutely being filled in these zones, first area that are used for the first material, wherein, the advantage that realizes in addition is can design more simply coating procedure itself by avoiding using be used to the veil that deposits other material.
The possibility that exists on the other hand is, in order to deposit described at least a other material in substrate, the same zone of using the first material coating of adopting veil to be used for blocking substrate surface, just can improve Economy thus in this point, can abandon removing the machinery reprocessing afterwards of excess material and can saving in addition the material of coating.
In a kind of preferred enforcement flexible program of this method, apply wherein at least a material according to the cool air injection method or according to the high-velocity flame spray method.The advantage of two kinds of flexible programs is, particle strikes in the substrate with very high speed, although by the method adopt be powder type material but still can particle is protoxydic realizes very thick bed thickness simultaneously making.Compare with other injection method in addition, jetted layers can be significantly improved thus in suprabasil adhesion, and can not obtain the too high thermal force of substrate simultaneously.The advantage that also realizes in this external cool air injection method is, in fact the material of powder type can not change ground-exception is to produce marginal layer-be coated in the substrate, so that this layer virtually completely reproduces the characteristic of material powder on the powder particle.This also is fit to the high-velocity flame spray method on less degree.
Another enforcement flexible program according to the present invention is set; as the such material of the first injection of material; the hardness of the described at least a other material that the hardness ratio of this material is sprayed greatly at least 20%, particularly at least 25%, preferably at least 30%; in order to give on the one hand thus the adaptation ability of sliding bearing necessity and to dirt particle or to the embeddability of the particle that produced by abrasion, and give on the other hand the needed hardness of sliding bearing and be used for improving wear resistance.
Preferred only apply described at least a other material in the zone at least one lateral edges of substrate surface at this.Can avoid better thus in the situation of hard bearing material by the danger that produce, that in sliding bearing, bite (Fressen) of too high seamed edge load, wherein, on the other hand after the adaptive end of slip surface to the bearing fit face of sliding bearing, namely when load was distributed on the whole bearing surface, sliding bearing also had sufficiently high intensity by harder zone line.
The possibility that exists in addition is that each sprays described material with a kind of different injection method, can take better material behavior into account thus, thereby further can improve material in the adhesion strength of substrate surface among the result.
Also possiblely be that deposition has at least a other material than the larger surface roughness of the first material and/or higher porosity.What can realize thus is, the oil that has improved sliding bearing at the running in stage of the sliding bearing surface topography that consists of by the surface in the zone that is made of at least a other material holds, the thus wearing and tearing of material in running in stage, particularly when this material is made of soft material, can be improved significantly.
A kind of special enforcement flexible program according to this method is set, and at least part of form with sign of described the first material applies.Except previously described advantage by the function decision, also realized thus bonus effect: after this sign is anchored in the layer securely, after using sliding bearing for a long time, this sign yet exists, so that sliding bearing can clearly classify, and for example when maintenance, also can mend more simply and order bearing of the same type.The advantage that this enforcement flexible program also has is that this sign not only is used for to the identification in principle of sliding bearing, and equally also can produce the function of the friction that improves sliding bearing but in addition.
A kind of enforcement flexible program according to sliding bearing is set, set up the connection between each zone that is consisted of by different material powders by the compression process of cold power so that by this connection procedure make the material that adopts during the sliding bearing aspect its characteristic not by or basically do not change by thermal force.
The reason of having mentioned owing to the front advantageously, anti-friction lacquer (Gleitlack) is arranged at least one side area of sliding layer of sliding bearing.
The possibility that exists in addition is that described at least two zones that are made of different materials have different bed thickness at least in part.Can realize thus particularly softer material in the bi-material, when applying this softer material with thicker bed thickness, in running in stage, mainly abut on the bearing fit surface, namely for example on the surface of axle, so that mainly carry out adaptive in soft zone and can avoid better thus wearing and tearing in the zone in the territory, hard area of the layer of sliding bearing.In this possibility that also exists be, material softer in running in stage is brought in the surface area of harder material by wearing and tearing, and next can be conducive to equally there adaptive to the bearing fit surface of bearing surface.
As mentioning, preferably apply the material that has the hardness less than other material in described at least two kinds of different materials with larger bed thickness.
Bed thickness poor preferably maximum bed thickness 10% and 30% between.Being lower than 10% is not enough to observe described desired effects.Be higher than 30% and can too prolong the running in stage of sliding bearing, two bearing surfaces stage during adaptive namely, make thus sliding bearing just reach too late its completely effect.
Layer, the sliding layer particularly in the zone with different materials and different heights by the structure sliding bearing, especially when increase regional circumferentially observed-had on two seamed edge zones of sliding bearing or side area-edge, be implemented in addition and construct one type lubrication groove or lubrication gap in the zone line, thereby can in running in stage, again reduce wearing and tearing.
The possibility that exists in addition is that described at least two different zones have different surface roughnesses, in order to can again control better or regulate thus the ability that keeps oil, in order to reduce thus wearing and tearing.
At this advantageously, the material that has less hardness has larger surface roughness than the material with larger hardness.

Possible is between each layer, namely for example to be provided with one deck binder couse form or the diffusion impervious layer form at least mesosphere between supporting member 2 and the bearing alloy layer 4 and/or between bearing alloy layer 4 and sliding layer 4 at least in addition.Binder couse or diffusion impervious layer can be by consisting of this common material, for example by aluminium lamination, tin layer, copper layer, nickel dam, silver layer or their alloy, particularly pairing gold formation.
Diffusion impervious layer has 1 micron to 3 microns little bed thickness usually.Binder couse can have maximum 0.3 millimeter bed thickness.
The bed thickness that bearing alloy layer 3 can have be selected from have 100 microns, the scope of preferred 300 microns lower limit and 3 millimeters, the preferred 1 millimeter upper limit, the bed thickness that supporting member 2 can have be selected from have 1 millimeter, the scope of preferred 2 millimeters lower limit and 20 millimeters, the preferred 8 millimeters upper limit.
According to the present invention, the sliding layer 3 of sliding bearing 1 by multiple, that is to say that at least two kinds of different materials consist of, these materials are arranged in the discontinuous zone in substrate, that is to say under the simple scenario to be set directly on the supporting member 2.If between sliding layer 3 and sliding bearing 1, should have the mesosphere, then therewith correspondingly the arrange structure that be stacked of described substrate by corresponding each layer consist of, namely for example consist of by the structure that arranges of supporting member 2 together with bearing alloy layer disposed thereon 4.
It is to be noted at this point, next aspect the present invention, only relate to more sliding layer 3.But self-evidently within the scope of the invention possible be, other layer of sliding bearing 1, the bearing alloy layer 4 that particularly exists in case of necessity, also make by discontinuous zone different, that have different materials according to the present invention, wherein, the combination of each layer also is possible, in this combination in these layers every layer or these layers two-layer at least each consisted of by multiple different material.For the situation of being made bearing alloy layer 4 by at least two kinds of different materials, these materials can be selected from aforementioned material, wherein, as long as sliding bearing 1 is made, particularly made by means of cool air injection or high-speed flame (HVF) injection by the preferred enforcement flexible program of this method, just can realize whole combinations of these materials.
Fig. 2 illustrates the greatly reduced graph of signal that carries out coating procedure with 5 pairs of supporting members of the first material 2.For this reason supporting member 2 be placed with veil 6-in Fig. 2 for the former of better clarity thereby veil 6 is shown certain distance-and by means of plater 7 material 5 is deposited on the first area 8 is arranged apart from the surface of supporting member 2.Implement in flexible program 1 from middle region extension until two distolateral seamed edges zones of supporting member 2 at this this first area 8, thus namely in the zone of lateral edges-along the necking down of two sides of the circumferential observation of sliding bearing 1-this first area 8 of existence.Correspondingly be formed with veil 6 or template for this reason so that the other zone 9 of these two necking downs is capped and thus in this first coating step not by material 5 coatings.
The possibility that also exists is, by the holding device of outside with the distance substrate, namely the little distance on the surface of supporting member 2 keeps veil 6, wherein, this distance can be selected from the scope of the upper limit of lower limit with 0.5 millimeter and 20 millimeters, is selected from especially the scope of the upper limit of lower limit with 1 millimeter and 9 millimeters.
Plater 7 comprises nozzle 10, and material 5 sprays from this nozzle.In addition, described plater comprises the different feeding mechanism for material 5 self-evidently, but these feeding mechanisms do not illustrate in Fig. 2.
In case veil 6 is just removed by material 5 coatings in described first area 8.Two zone 9 usefulness are different from the other material coating of material 5 in ensuing coating step.Can so carry out coating at this so that substrate, namely supporting member 2 whole surface on the inner side surface, that is to say can be on the surface of the structural element that will support, with this other material coating.In other words, namely same by described other material coating by the zone 8 of material 5 coatings before.In this enforcement flexible program of this method, in the process step that finishes, carry out the particularly reprocessing of machinery, for example bore by smart, the material that is coated in the surplus on the zone 8 in this essence is bored is removed again, thereby two zones 8,9, that is to say material 5 and described other material, visible and can be placed in and abut on the member that will support on the sliding bearing of completion.
The possibility that for this reason exists in a kind of method flexible program is that zone another veil of 8 usefulness covers and only has the other material of zone 9 usefulness again by plater 7 coatings.
Produce sliding layer 3 by the method, this sliding layer by at least bi-material of different nature consist of-also can be the zone 8,9 of sliding layer 3 structures more than two at sliding bearing 1 when needing, and possiblely in addition be, the material more than two kinds of different nature is adopted in a plurality of zone, wherein, the material that consists of sliding layer 3 is with substrate, namely directly contact with supporting member 2 in this case.Favored area 8 hard material coating, and zone 9 usefulness softer material coating by comparison.
The other material that is used for zone 9 can be selected from the group that comprises AlSn20Cu, AlSn40, AlSn40Cu, AlSn10Cu.
Preferred combination of materials for example is CuSn5Zn/AlSn20Cu or CuPb20Sn/AlSn40Cu.But be noted that and use in principle from alloy well known in the prior art, as to be used for sliding layer as material 5 or other material.
In a kind of preferred form of implementation, perhaps by means of cool air injection or carry out the coating of material 5 and at least a other material by means of high-velocity flame spray, wherein, the combination of these two kinds of methods also is possible, the harder material 5 that for example is used for zone 8 applies by means of high-velocity flame spray, and the softer material that is used for zone 9 applies by means of cool air injection.
The cool air injection method is known in sliding bearing manufacturing field in principle.For example the WO2005/033353A2 from the applicant has described a kind of method for make composite material in the situation that adopts cool air injection.By DE102004043914A1 also known come sliding bearing is carried out coating by means of cool air injection.
In cool air injection, the material of known material, particularly powder type is accelerated to relatively high speed, and next with high-speed impact to the surface of substrate, wherein, each particle connection fastened to each other in this bump, thereby produce closely layer.
Similarly, the material of powder type is accelerated with the basad surface of high speed, thus equally by striking on the substrate surface and producing closely layer.But in high-velocity flame spray, usually adopt than temperature higher in the cool air injection under the same case.But the favourable part that two kinds of methods provide is, owing to the brief stay time of particle in beam produces (oxidarme) layer of hypoxemia, so that the layer that produces has such composition basically, these compositions have the constituent element of powder type.
Because lower temperature preferably adopts cool air injection for the other material that is used for as regional 9 coatings, this is because these materials preferably comprise low-melting element, for example tin or bismuth.
The material of powder type is to be coated on the substrate surface at a high speed, carry out at a high speed the compression process of cold power by this, thereby in the borderline region between zone 8 and 9, two kinds of different materials abut against each other there, although this bi-material has different compositions, also can generate by the compression of cold power the connection of this bi-material, even so that the sliding layer 3 material difference in layer that is made of different materials also has high strength of connection.
Realize and being connected of substrate surface by high stroke speed in addition, that is to say on substrate surface adhere to relatively tight, thereby realize layer firm bonding structure, that is to say composite material.If but sliding layer 3 suprabasil, when that is to say that strength of connection on supporting member 2 is enough, the possibility that produces like this is: for example passed through method machinery and/or chemistry before coating, from well known in the prior art, make the surface of substrate, the i.e. surface roughening of supporting member 2 for example such as these methods.
Fig. 2 illustrates: the semi-finished product of preformed halfliner form are coated.But the possibility that also exists within the scope of the invention is that coating is carried out on smooth surface, and next just implements the mechanically deformation to the sliding bearing halfliner after finishing whole coating procedure.Advantage at this is: material 5 is connected with the surface of substrate with at least a other cold power of material ground, this is because in fact do not causing in the material that applies with powder type during the deformation process or only causing small variation thus, thereby does not need in case of necessity to carry out hot reprocessing after deformation process.
The speed of particle depends on the material of splash in cool air injection.Therefore, for example for soft material such as tin, speed may be between 150 meter per seconds and 350 meter per seconds, and with it relatively, speed is 400 meter per second to 1100 meter per seconds for copper.Hard material can require higher speed.
Can adopt inert gas such as argon or preferred nitrogen as vector gas.
Amount of powder (Pulvermenge) can be with size of powder particles and desired layer characteristic, select relatively such as hardness and porosity, and this amount of powder is typically between 5 gram/minute and 50 gram/minute.Select higher value for multiporous layer, and layer needs less amount of powder more closely.
These parameters are similarly for HVOF sprays, but also have in addition gas type.With desired combustion temperature for example can adopt relatively acetylene (until 3000
0C) or hydrogen (until 2800
0C) or corresponding mixed gas, for example synthetic gas.
The speed of particle depends on again material as mentioned above.Extra also will consider the waiting time (that is to say nozzle apart from the distance for the treatment of coating surface) of powder in beam, this is because the surface of oxidation particle controllably.
Except sliding layer 3 only by the enforcement flexible program of metallic material structure, implement the possibility that flexible program exists and be according to a kind of, particularly with those zones 9 softer material coating, that consisted of by anti-friction lacquer with or not with the situation of veil 9 under by this anti-friction lacquer splash is made in zone 9.Can be applicable in principle all known anti-friction lacquers in the sliding bearing technical field.Can adopt for example teflon as anti-friction lacquer, fluorine-containing resin, perfluoro alkoxy-copolymer for example, perfluoro alkoxy-teflon-copolymer, ethylene-tetrafluoroethylene copolymer, polychlorotrifluoroethylene, the ethylene-propylene copolymer of fluoridizing, polyvinylfluoride, polyvinylidene fluoride, alternate copolymer, statistical copolymer, fluorinated ethylene propylene copolymer for example, polyesterimide, bismaleimides, polyimide resin, Carboranmide for example, aromatic polyimide resin, without the hydrogen polyimide resin, polytriazoles PMA acid imide (Pyromellithimide), polyamidoimide, aromatic polyamidoimide particularly, the poly(aromatic easter) acid imide, come modification by isocyanates in case of necessity, Polyetherimide, come modification by isocyanates in case of necessity, epoxy resin, epoxy resin ester, phenolic resin, polyamide 6, polyamide 66, polyoxymethylene, silicone, poly(aromatic easter), poly aryl ketone, PAEK, polyarylether-ether ketone, polyether-ether-ketone, polyether-ketone, polyvinylidene fluoride, polyethylene sulphide, propine sulphide, polytriazoles PMA acid imide (Pyromellithimide), polyesterimide, the polyarylphosphorus compound, polyvinyl sulphide, polyphenylene sulfide (Polyphenylensulfide), polysulfones, polyether sulfone, polyarylsulfone (PAS), poly-fragrant oxide (Polyaryloxide), polyarylphosphorus compound (Polyarylsulfide) and the copolymer that is consisted of by them.
Preferred anti-friction lacquer comprises that in drying regime 40 % by weight are to the MoS of 45 % by weight
2The polyamidoimide of 20 % by weight to the graphite of 25 % by weight and 30 % by weight to 40 % by weight, wherein, can also in anti-friction lacquer, the share take summation as maximum 20 % by weight comprise grit in case of necessity, for example oxide, nitride or carbide, these grits replace the share of solid lubricants.The advantage that this anti-friction lacquer has is, softer layer region 9 is special also to work during adaptive and naturally produces certain wearing and tearing at this in that the counterpart that will support is carried out in the running in stage of sliding bearing 1, so that this anti-friction lacquer can be with the form wearing and tearing of relatively little particle, thereby next these particles neither damage the surface of sliding bearing, sliding layer 3 namely, also do not play interference effect in the oil circulation.
Preferably adopt the material that is used for zone 8 in order to make sliding layer 3, the hardness of the material that the hardness ratio that this material has is other greatly at least 20%.For example material 5 Vickers hardness that can have in the situation of the test force of 10 gram forces (Pond) is selected from the scope of the upper limit of lower limit with 30HV and 40HV, and the hardness that other material has is selected from the scope of the upper limit of lower limit with 50HV and 70HV.
In all methods, also there is in principle following possibility, namely, if as previously described like that also in the situation that does not have veil 6 whole ground apply softer other material, this softer material not by or not exclusively be removed and thus serve as so-called adjustment layer.
The possibility of existence is in addition, particularly compares with the first material 5, and softer other material deposits with higher surface roughness in zone 9.This for example can realize in the following way, that is, with less speed particle is sprayed to the substrate for the treatment of coating.At this, the surface roughness between two zones 8,9 can have at least 10% difference, and namely zone 9 has high at least 10% surface roughness.Zone 9 maximized surface roughness profile height Rz can be selected from the scope of the upper limit of lower limit with Rz10 and Rz50 according to DIN EN ISO4287.Preferred maximized surface roughness profile height Rz is Rz35 to the maximum according to DIN EN ISO4287.
The possibility that exists in addition is that described other material is for example realized by the powder mass flow of raising time per unit or by reducing jet velocity to compare higher porosity deposition with the first material 5.At this, the porosity of described other material can be than the porosity of the first material 5 greatly at least 10%, and particularly at least 20%.
Be mentioned to: also possiblely in principle be, also can be opposite with the situation in the preferred enforcement flexible program about the relation of surface roughness and porosity.
