Definitions
- the invention relates to a piston ring of a carrier material, in particular of steel or a cast material, with a wear protection coating of a periodically constructed multilayer coating system, each periodicity consisting of at least two individual layers of metal nitrides.
- the running surfaces of piston rings in internal combustion engines are subject to wear during their use.
- the running surfaces of the piston rings are provided with a protective layer.
- DE 4441 136 A1 discloses a pressure ring for a piston of a piston-cylinder arrangement of a reciprocating internal combustion engine.
- the abrasion-resistant coating consists of a nitride, such as CrN, Cr 2 N, TiN, Ti / TiN or ZrN.
- the coating consists of only a single layer. References to a multilayer coating system can not be found in DE 4441 136 A1.
- JP 2002-256967 AA discloses a sliding member having an abrasion-resistant coating.
- a piston ring is mentioned which has a layer based on metal nitrides. Also in this Pre-publication, there are no indications of multilayer coating systems.
- a wear protection coating for piston rings in internal combustion engines which consists essentially of chromium carbides, chromium, nickel and molybdenum.
- a powder consisting of these components is applied to the piston rings by means of high-speed flame spraying.
- piston rings for internal combustion engines which are provided with a multi-layer system, the individual layers have the same metallic component and differ only in nitrogen content.
- the layer thicknesses of the individual layers are given as ⁇ 1 ⁇ m.
- the layers are applied by means of a PVD process, in particular an arc process.
- DE 10 2004 028 486 A1 describes a sliding component, such as.
- piston rings for internal combustion engines which has a coating of several individual layers, which consist of alternating chromium and chromium nitride.
- the chromium nitride layers may consist of CrN, Cr2N or mixtures thereof.
- the coating process is controlled so that the Chromnitrideinzellenagen each have a hem made of Cr2N and a core of CrN on both sides.
- Each individual layer is at least 0.01 ⁇ m thick.
- the maximum thickness is 10 ⁇ m.
- the total thickness of the coating is given as 5 to 100 ⁇ m.
- the object of the invention is therefore to provide a piston ring with a multi-layer system, which is less susceptible to cracking with good wear resistance.
- a multilayer coating system of metal nitride layers on the one hand has good wear resistance and on the other hand has a low susceptibility to cracking due to the use of different metals for the adjacent individual layers within the periodicity.
- the hardness and the elasticity properties of the individual layers can be coordinated so that significant phase boundaries occur. If - as described in the prior art - only one metal is used and only the nitrogen content is varied, do not form so clear Phase boundaries that they could exert a positive influence on the cracking.
- piston rings with such a multi-layer system is significantly higher than in piston rings with a conventional single layer or with a multi-layer system, which, although also made of nitride layers, but in which only the nitrogen content is changed with the same metallic component.
- the individual layers comprise nitrides of at least one metal from the group titanium (Ti), zirconium (Zr), hafnium (Hf), vanadium (V), niobium (Nb), tantalum (Ta), chromium (Cr), molybdenum (Mo) and tungsten (W) on.
- nitrides of the metals mentioned are possible. These may be stoichiometric phases or non-stoichiometric phases or mixtures thereof.
- CrN should be understood to mean one or more phases of the system Cr-N, and this analogously applies to the other systems. Depending on the coating process, one or the other combination may possibly be preferred.
- CrN for at least one single layer of periodicity.
- CrN can be combined with the nitrides of all other metals of the group mentioned in the multilayer coating system.
- Preferred single-layer combinations are CrN / TiN, CrN / ZrN or CrN / VN.
- the periodicity may also have more than two individual layers, preferably up to four individual layers. Two individual layers are preferred insofar as the production costs increase significantly with increasing number of individual layers per periodicity.
- At least one individual layer of the periodicity contains> 0 to 15% by weight, in particular 3 to 8% by weight, of at least one of the doping elements aluminum, silicon or carbon.
- These doping elements cause the wear protection layers to have higher oxidation resistances and lower coefficients of friction.
- the doping elements of adjacent individual layers are different.
- the differences in the properties of the adjacent individual layers are additionally increased by the addition of the doping elements, with the result that the differences in the material properties of the adjacent individual layers occur more clearly at the phase boundaries, which is particularly advantageous for preventing crack propagation perpendicular to the individual layers effect.
- At least one of the individual layers of the periodicity contains nitrides of at least two metals from the group Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W, with adjacent individual layers differing in at least one metallic element.
- Preferred metal combinations of the nitrides for at least one individual layer of the periodicity are TiZrN, TiAIN, CrSiN, CrZrN, CrTiN or CrVN.
- the metal combinations mentioned can also be mentioned Have doping elements.
- the advantages of these metal combinations for the individual layers are that the respective material properties can be varied and adapted.
- At least one intermediate layer of at least one of the metals Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W can be provided.
- the advantages of these interlayers are that, as ductile metals, they are capable of redirecting or stopping crack propagation and of significantly increasing the overall ductility of the multilayers dressing, so that overall residual stresses can be reduced. This is important in particular for the deposition of wear protection layers, which are deposited to increase the service life with a higher layer thickness.
- At least one adhesive layer is provided between the carrier material and the first single layer, which may consist of at least one of the metals Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W.
- One advantage is that the otherwise customary nitration of the surface of the carrier material, in particular of the steel, can be dispensed with, whereby a work step is saved.
- the adhesive layer material is identical to the material of the intermediate layer or to the metal of a single layer.
- the deposition process then needs to be modified only by the composition of the process gas.
- Preferred adhesive layer materials are chromium and titanium, in particular in support materials made of steel, because they have a particularly good adhesion to steel materials.
- the thickness of a periodicity is preferably 30 nm to 1 .mu.m, preferably 30 nm to 500 nm, more preferably 30 nm to 120 nm and particularly preferably 60 nm to 120 nm.
- the lower limit of the periodicity of said value ranges is> 30 nm.
- the thickness of a single layer is preferably 15 nm to 150 nm.
- the thickness of the multilayer coating system is preferably 10 ⁇ m to 50 ⁇ m, in particular 10 ⁇ m to 30 ⁇ m. These thicknesses are below the thicknesses required for layers of the prior art, e.g. B. for a single-layer chromium nitride are needed to ensure the same service life. By reducing the thickness of the wear protection coating material and time is saved in the production of the coating.
- the multilayer coating system is applied by means of a PVD process.
- the metal nitrides TiN, ZrN, VN, CrN and MoN can be applied particularly favorably.
- the arc process is provided to apply the multilayer coating system.
- the multilayer coating system can also be applied by means of a CVD process.
- the wear protection coating is particularly suitable for compression rings and for oil rings.

- Each periodicity 11 consists of two individual layers 20, 21, wherein only one periodicity 11 is shown for the sake of clarity.
- FIG. 4 shows an enlargement of the detail Y from FIG. Due to inevitably existing unevenness on the surface of the substrate 3, a more or less pronounced waveform forms for the individual layers, which is smoothed by the mechanical finishing on the surface.
- a crack 5 is drawn in the surface layer 21, which extends from the surface into the interior. This crack 5 ends at the first phase boundary 30. Further penetration of the crack 5 into the interior of the multilayer coating system is prevented by this phase boundary 30. The clearer the differences in the material properties between the individual layers 20 and 21, the more defined the cracks are deflected.
- FIG. 5a shows a scanning electron micrograph in which the individual layers consist of CrN and ZrN.
- FIG. 5b shows a scanning electron micrograph in which the individual layers consist of CrN and TiN.
- Table 1 shows the preferred metals of the metal nitrides in a matrix. All metal nitride combinations for the adjacent individual layers are provided with the exception of the identity according to the invention. The most preferred metal nitride combinations are indicated by X.

- the system numbers 1, 2 and 4 denote metal nitride combinations, which can be deposited particularly favorably in the arc process.
- Table 2 lists the total layer thicknesses, periodicities and layer hardnesses. To test the wear resistance, model tests with lubricated, reversing sliding stress were carried out with these piston rings.
- the counter-body consisted in each case of a cylinder barrel segment made of cast iron (GOE 300, material of the Applicant), as a lubricant was used to speed up a synthetic ester without additives.
- FIG. 6 schematically shows a multilayer coating system 10 according to a further embodiment. Between the periodicities 11, an intermediate layer 25 is provided in each case. In addition, an adhesive layer 26 is provided between the first single layer and the carrier material. It is also possible to provide only one adhesive layer or only intermediate layers.
