Definitions
- the present invention relates to a method for galvanic deposition of nickel, cobalt, nickel alloys or cobalt alloys in one galvanic bath using a nickel compound or cobalt compound such as electrolytes containing sulfates or sulfamates or chlorides.
- a nickel compound or cobalt compound such as electrolytes containing sulfates or sulfamates or chlorides.
- electrolytes for electrodeposition are, for example known from DE 25 58 423, DE 22 18 967, US 2,470,775 and EP 0 835 335.
- At least one anode and at least one cathode are used for the deposition periodic current pulses are applied to the bath.
- Such procedures using current pulses are, for example, from the prior art the already mentioned publications US 2,470,775 and EP 0 835 335.
- the object of the present invention is therefore a method for galvanic Deposition of nickel, cobalt, nickel alloys or cobalt alloys to be provided in a galvanic bath in which at least one Anode and at least one cathode of the bath with periodic current pulses is applied and with the nickel or cobalt layers or layers a nickel or cobalt alloy can be created that are inseparable from other components can be connected, especially with others Components can be welded.
- an electrolyte which contains the corresponding nickel compounds or cobalt compounds, in particular sulfates or sulfamates or chlorides.
- periodic current pulses are applied to at least one anode and at least one cathode of the bath, ie a so-called pulse plating process is used.
- a deposition body on which a layer of the corresponding material is to be deposited normally acts as the cathode.
- Particularly advantageous properties of the deposited layer, in particular with regard to the strength and the extensibility, can be determined for these parameter ranges.
- At least one contoured anode is used for the deposition whose contour is adapted to the contour of the deposition body to deposit the nickel, cobalt, nickel alloy or cobalt alloy is.
- This adaptation of the anode contour can in particular an almost constant distance over the entire contour of the deposition body be achieved between the anode and the deposition body, which is a enables more uniform deposition.
- a contoured anode In the event that several anodes are provided in the bath, at least for one of the anodes closest to the deposition body are used, a contoured anode.
- the effect of contouring affects the closest anode the anode is stronger than for anodes further away, i.e. that for these more distant anodes can each be used without contouring that are less expensive and independent of the special shape of the deposition body can be used. So can through this suitable combination of contoured and non-contoured Anodes an optimum in terms of the quality of the deposition as well as the necessary effort can be achieved.
- a contoured container for example, can be used to form the contoured anode be used for the ions of the nickel to be deposited or Cobalt or the nickel alloy or cobalt alloy is permeable and the with bodies made of nickel, cobalt or a nickel alloy or cobalt alloy is filled.
- Special containers for such bodies are basically made DE 25 58 423 in the form of titanium or plastic baskets known there with Nickel pellets are filled, but there is no contouring of the container is provided.
- a solid electrode body can be used, the at least one Coating of the nickel, cobalt or the deposit to be deposited Has nickel alloy or cobalt alloy or even made of solid Nickel, cobalt or a massive nickel alloy or cobalt alloy.
- a targeted Influencing the deposition is necessary for different areas of the Separator body should be different.
- This influence can in addition or alternatively to the aforementioned measure of the contoured Anodes are made.
- the deposition body at least for part of the total deposition time is partially shielded by current shutters. In the shielded areas then during the time these areas are shielded, reduced deposition compared to the unshielded Areas. This can have a local influence on layer properties such as in particular the layer thickness, but possibly also the mechanical layer properties realized on the deposition body become.
- the flow orifices in those areas of the deposition body be arranged in which a preferred deposition he follows. This can result in excessive layer growth in these areas compared to other areas can be prevented and thus a more homogeneous Layer growth realized over the entire deposition body become.
- It can preferably be a removal of disruptive foreign elements or other suspended particles from the bath are provided, to get the purest possible electrolyte solution.
- cleaning the electrolyte using activated carbon and / or hydrogen peroxide can be used for cleaning of the electrolyte before the start of the deposition 0.5 g / l to 5 g / l, in particular 1g / l to 3g / l activated carbon can be used and 0.5 ml / l to 3 ml / l, in particular 1ml / l to 2ml / l 30% hydrogen peroxide can be used.
- a selective bath corresponds to a galvanic bath, in which by a targeted control the flows a targeted separation of foreign elements and thus their removal from the electrolyte.
- Electrolyte then ideally contains only the desired elements, in In the case of a nickel electrolyte then ideally only nickel or nickel alloys in the compounds mentioned at the beginning, in the case of a cobalt electrolyte ideally only cobalt or cobalt alloys in the beginning mentioned connections.
- the cleaned electrolyte is then the galvanic Bad fed again.
- the electrolyte can also be circulated, wherein the electrolyte is circulated by at least one circulation pump and the electrolyte is returned to the bath by means of nozzles.
- nozzles can now be designed and arranged in the bath that the circulation of the bath is promoted by the nozzles and / or a flow of the electrolyte directed onto the deposition body is achieved.
- the nozzles do not only serve the purpose of Circulation and return of the electrolyte to the bath, but through this optimized type of return, the separation process in the bathroom is favored, because there is always an optimal mixing or targeted feeding of a as pure as possible electrolyte to the deposition body is guaranteed.
- the method according to the invention is basically for the production of the most varied Suitable components that are later unsolvable with other components connected, for example to be welded.
- the procedure is however Particularly suitable for the production of components that are subject to high loads are exposed.
- Components are used that are subject to high loads in later operation, and therefore must have sufficient strength, but still should have sufficient elasticity, such as load-bearing mechanical structures, components for kilns or similar arrangements with high thermal stress etc. by varying the parameters
- the achievable strength of the method according to the invention is also the same Extensibility of the deposited layer over a relatively wide range adjustable, as will be explained in more detail in the further text.
- This special galvanic bath can be used to implement special training of the aforementioned method can be used.
- the at least one contoured anode is contoured Container is formed with bodies made of nickel or cobalt or a nickel alloy or a cobalt alloy can be filled.
- anodes are arranged in the bath, only that of the deposition body closest anodes are designed as contoured anodes are.
- the other anodes also have a certain one Have a contour, but in this case only the contour of those should Anodes that are closest to the deposition body to the contour of the Separator body to be adjusted.
- the contouring can only be in a spatial direction e.g. in the longitudinal direction of the anode, or it can also take place in more than one spatial direction, e.g. additionally perpendicular to Longitudinal direction.
- the cleaning device can be a filter device, in particular an activated carbon filter, and a selective bath. This allows both Suspended particles suspended in the electrolyte as well as unwanted particles Foreign elements are removed from the electrolyte.
- a galvanic bath with an electrolyte which nickel compounds contains.
- a galvanic bath is also included Cobalt compounds conceivable.
- Electrolytes known as prior art as nickel compounds or cobalt compounds for example nickel sulfate and nickel chloride or also nickel sulfamate and nickel chloride are provided, as well as in the case of the cobalt compounds the corresponding sulfates, sulfamates or chlorides.
- the composition of the electrolyte is on the prior art cited at the beginning.
- Additives may be provided in the electrolyte, such as that in the EP 0 835 335 or DE 22 18 967 cited sulfonated naphthalene or those in US 2,470,775 column 3 paragraph 2 additives mentioned.
- pulse plating method is now used for the deposition applied, i.e. the application of anodes and cathodes to the bath with periodic current pulses, which in principle come from the state cited at the beginning is known in the art.
- FIG. 1 shows the dependence of the yield strength (0.2 yield strength) R p 0.2 , the strength R m and the ductility A 5 of a nickel layer deposited according to the aforementioned method on the charge ratio Q A / Q C for current density ratios I A / I C between 1.3 and 1.4 describes. It is shown here that with a charge ratio between 35 and 40 the strengths and the extensibility are in a medium range of values, ie an optimal balance is found between the extensibility and strength of the deposited layer. If the charge ratio is increased, the ductility continues to increase, but at the same time the strength continues to decrease, so that the deposited layer does not have sufficient mechanical stability.
- FIG. 2 schematically shows the structure of the bath for realizing the invention, which is filled with an electrolyte as described above.
- a deposition body 2 such as a combustion chamber a rocket engine in a bath 1.
- a coating is now to be generated, for example, from nickel.
- at least one anode 3 is let into the bath 1, the Anode 3 is contoured in such a way that it conforms to the contour of the deposition body 2 is adjusted.
- the contouring can only be in one spatial direction e.g. in the longitudinal direction of the anode 3, or it can also be in more be provided as a spatial direction, e.g. additionally perpendicular to the longitudinal direction. 2 shows only a single anode 3 for the sake of simplicity shown.
- anodes 3 shows a possible arrangement of several anodes 3a, 3b in a bath 1, being those anodes 3a that the deposition body are closest, as contoured anodes are formed, because the positive influence of contouring is most noticeable there.
- the anodes 3b further away, on the other hand, can be used as universal in the simplest case, flat anodes are formed, for which each standardized anode shape is applicable. Consequently, only those of the deposition body 2 closest anodes 3a to the adapt special shape of different deposition body 2.
- This anode concept provides an optimization of the effect of the anodes 3a, 3b at the same time maintaining an arrangement that is as universal as possible.
- the contoured anode 3 in FIG. 2 is formed by a contoured container 8, which is designed for example as a titanium basket and therefore permeable is for the nickel ions necessary for the deposition.
- the container 8 can also additional sheaths that are also permeable to nickel ions be surrounded by a bag, for example.
- the nickel is here introduced in the form of small nickel bodies 9 in the container 8 and can in a simple way with a gradual consumption of nickel during of the deposition process can be easily refilled.
- a device 4 controls the anode 3 and the cathode acting deposition body 2 in the bath 1 with periodic current pulses to carry out the pulse plating process described.
- the appropriate areas are shielded, in which an increased separation such as surveys. Otherwise one can less separation in other areas such as deepening be balanced.
- the current diaphragm 5 can for example in the bathroom 1 slidably or completely removable, for what suitable facilities must be provided.
- a cleaning device 6 is used to clean the electrolyte from interfering Foreign elements and floating particles during the deposition process and takes place with the help of activated carbon filters 10 and a selective bath 11, shown only schematically in FIG. 2.
- the removal and return of the electrolyte into the bath is carried out by appropriate supply and discharge lines. This enables a particularly high purity of the electrolyte and its almost complete liberation of foreign elements, especially foreign metals, as well as from suspended particles.
- the proportion of foreign elements Fe, Cu, Cr, Al, Zn, Co in the nickel bath can be reduced to values below 0.1 mg / l, which the properties of the deposited layer also benefit because through such a reduction in the proportion of foreign elements, the extensibility the deposited layer is further improved and an additional one guaranteed high or even higher strength of the deposited layer.
- the bath also has a circulating device shown schematically in FIG. 2 13 for circulation of the electrolyte, which from a circulation pump 12 and suitably designed and suitably arranged nozzles 7 for There is recycling of the electrolyte.
- a circulation pump 12 and suitably designed and suitably arranged nozzles 7 for There is recycling of the electrolyte.
