- a nickel alloy is provided, which is produced by a chemical deposition method and has a thickness of about 2 pm.
- a structured Chfom solid particle layer with a crack network is known.
- Festetoffp are stored.
- the layer is produced electrolytically and should be suitable for piston rings.
- a multi-layer, electro-deposited chromium layer is known, for example, from DE 10 2009 045 889 A1.
- the thickness of individual layer layers amounts to, for example, a maximum of 7 pm, in particular a maximum of 3 pm.
- the layers may contain foreign ions such as carbide, Contain molybdenum, vanadium or tungsten ions.
- PVD physical vapor deposition
- the PVD (phyaical vapor depoeition) processes can essentially be built up from carbon and are also referred to as DLC (diamond-clear carbon scat.)
- DLC diamond-clear carbon scat.
- An example of such a coating is disclosed in DE 10 2006 029 415 A1
- a support layer containing, for example, chromium.
- the invention has for its object to further develop a coating of a metallic component, for example Wharmlagerbauteits, in particular with regard to the properties relevant in cooperation mil lubricants.
- the coated component has a metallic substrate and a chromium feed of less than 2 ⁇ m deposited thereon in the PVD process. No further damage is done to the chrome layer. However, it is formed on the component surface, that is on the surface of the chrome layer, a compound of chromium and at least one other element. This compound is produced either as part of the production process of the components or only after the pre-commissioning of the prey by the prevailing operating conditions, in particular exposure to lubricant. The thickness of the chromium layer is practically not increased by the connection with the further element.
- the invention is based on the consideration that lubricants in the rolling bearing technology can have both positive and negative effects on the life of a bearing. Negative effects are conceivable in particular by decomposition products or by-products of lubricants.
- Hydrogen may play a role in welding metallurgies on the surface of metallic components.
- Atomic hydrogen is incorporated in the galvanic Abschekjung a metal layer process-related in the metal layer, whereby a diffusion of hydrogen in the base material is possible.
- the layer thickness to very low values of a maximum of 2 pm, preferably less than 1 pm. particularly preferably less than 500 nm, limited, wherein the layer is not produced wet-chemically, but is deposited from the gas phase.
- the chromium layer deposited from the gas phase is always referred to simply as a PVD layer, with the result that it is delimited by a layer deposited from an aqueous phase.
- layers which have undergone CVD (chemical vapor deposition), PA-CVD (physical assisiated chemical vapor deposition) method, or the O-CVD (metal organic chemical vapor deposition) method are prepared, are among the In all cases, this coating has the advantage that it forms a crack-free barrier against environmental influences, in particular against hydrogen ..
- the chromium oxide which forms as a surface layer, forms an integral part of the coating of the component, which can increase in the course of the operation of the component, whereby the entire coating remains as a chromium layer referred to as.
- the coating chamber is at the end of the coating process, which takes place in a coating chamber at a temperature between 130 "C and 160'C, preferably at a temperature of about 150 * C, vented to the surface of the ready-finished
- aeration is also understood to mean the addition of a synthetic, oxygen-containing gas mixture or of pure oxygen specified temperature range at the conclusion of the coating process for the formation of an extremely thick and dense oxide layer, which prevents any adverse interaction with harmful elements or compounds of a lubricant during operation of the thus coated BauteilHs, in particular bearing component.
- nitrogen can also connect to the chromium layer as a further element, in which case chromium nitride is formed as a particularly resistant barrier against environmental influences.
- the chromium nitride is in the context of the formation of the total designated as chromium layer PVD coating, for example, by a reactive PVD sputtering applied, preferably, the chromium nitride nanokristallkn in the coating in the form of various Cr, phases before.
- the proportion of Cr 2 N bonds is preferably more than 70%.
- the hardness of the coating of chromium and at least one compound which contains at least one further element other than chromium is between 800 and 1200 HV 0.3.
- the coating is preferably at least 100 nm thick.
- the process for producing a coating regardless of the technical field of application, comprises the following features:
- rolling stock. is made of a metallic substrate, - On the substrate by means of vapor deposition a Chromsc light is applied with a thickness of less than 2 pm, which forms the Werk Swissoberflöche and not further coated.
- the chromium layer is produced directly on the base material without an intermediate layer and can be overridden in the rolling bearing application field.
- the workpiece is, for example, a bearing ring or a rolling element of a bearing of a wind turbine.
- Fig. 1 a according to the invention coated with chromium in the PVD method
- a in Fig. 1 generally designated by the reference numeral 1 component, namely WälzJagerbautell, for example, inner ring, outer ring or Wäfek ⁇ rper is made of a metallic base material, also referred to as a substrate 2, prepared on soft a Beschtehtung 3 is upright,
- the coating 3 consists largely of chromium and is produced in the PVD process.
- a chromium oxide layer 4 which flows from an underlying layer directly to the base material, namely bearing steel.
- 100Cr6 or M50NIL is to be distinguished from adjacent chrome layer 5.
- the thickness of the chromium oxide layer 4 in relation to the total thickness of the coating 3 is shown in FIG. 1 not shown to scale.
- the total thickness of the coating 3 is 1 to 2 pm.
- the coating 3 has neither defects nor elevations, for example in the form of so-called droplets.
- the Chromoxidschictit 4 is an impermeable barrier. Even with a slight, not up to the base material protruding injury of the coating 3 whose protective effect is permanently maintained, since a new chromium oxide layer 4 as Diffusionsbamere on the component 1 is formed.
- the effect of the coating 3 is given in addition to their function as a barrier layer by katar table effect.
- the protective effect of the coating 3 is due not only to the ChromoxkJschlcht 4, but also to the fact that due to the production of the coating 3 by A separation from the gas phase, in contrast to galvanically generated layers no hydrogen In the coating 3 is installed.
- any hydrogen atoms present in the coating will diffuse into the component 1.
- the structure of a conventional, electrochemical wear protection layer ⁇ is in Fig. 2 in a representation analog Flg. 1 illustrates.
- the wear protection layer 6 has cracks 7. At least part of these cracks 7 goes to the base material 2 (substrate).
- wear protective layer ⁇ environmental influences, especially in the form of hydrogen 8, attack freely on the base material 2 of the component 1. There is no mechanism to stop such influences.
- Flg. 8 Plotted in the form of dots there is a significant, harmful amount of hydrogen 8 Within the wear protection layer 6.
- This hydrogen 8 diffuses over time in the substrate 2 and degreased there its damaging effect, which ultimately, together with other influences, in particular mechanical Stress, can lead to WEC.
- Such a damage mechanism is reliably avoided with the coating according to FIG. 1.
- the coating 3 of the component 1, which consists mainly of chromium, of the component 1 according to FIG. 1 can be subjected to high mechanical loads and permanently connected to the substrate 2, without the risk of spalling.
- the hardness of the coating 3 is 800 to 1200 HV 0.05.
