Description

Method for manufacturing components with a nickel base alloy as well as components manufactured therewith
The invention relates to a method for manufacturing components with a nickel base alloy as well as to components manufactured with this method. With this solution, manufacturing the most differently shaped components in various three-dimensional geometries is possible. The components, thus manufactured, may also represent porous structures or may comprise such porous structures.
With the nickel base alloys which are known per se, different components are allowed to be manufactured of course, wherein this can be primarily achieved with the known shaping methods. Thus, such components are allowed to be manufactured as cast parts which can be subsequently cold-worked or warm-worκed again, as the case may be. In particular during such a cutting shaping treatment, however, problems arise due to the mechanical properties of such nickel base alloys.
Furthermore, it has been proposed to modify components made of nickel by means of sintering methods, wherein the formation of solid solution or the formation of intermetallic phases ( preferentially of NiAl) should be achieved by sintering in order to achieve an improvement of the properties of such components. However, particularly in this form, the thermal properties of such components could be merely improved, and as a result the mechanical properties have not been improved in the desired form.
Therefore, it is an object of the invention to predetermine ways by means of which most differently shaped components are producible with nickel base alloys which comprise improved mechanical properties.
According to the invention, this object is solved with a method which comprises the features of claim 1. The components, thus manufactured have the features mentioned in the claims 17 and 18.
Advantageous embodiments and improvements of the invention can be achieved with the features described in the subordinate claims.
For the production of components with a nickel base alloy, the proceeding in accordance with the invention takes place such that a substrate core consisting of pure nickel or a nickel base alloy will be provided with a surface coating at least in areas. The surface coating is formed from a binding agent as well as from a metal powder. The metal powder to be employed according to the invention includes additional alloy forming elements which are still to be referred to subsequently, in addition to a content of at least 20 wt% of nickel.
A substrate core consisting of a nickel base alloy should include nickel of at least 20 wt%.
The metal powder to be employed according to the invention may be a powder of the respective nickel base alloy but also a powder mixture of the respective alloy forming elements with the nickel which has been preferably subjected to high energy grinding.
According to the invention, the substrate core provided with the surface coating is subsequently subjected to a stepped thermal treatment. On that occasion, in a first step the binding agent is expelled from the surface coating. Subsequent to expelling of binder agent sintering of metal powder is then achieved. During sintering, sinter-fusing of a nickel substrate core and/or a solid surface coating formed of a nickel base alloy is developed.
In case if a substrate core made of nickel base alloy has been employed as a semi-finished product, the content of nickel which is included in the metal powder should be smaller than the nickel content in the substrate core material.
The thermal treatment, however, at least such sintering should be carried out at temperatures of above 1000 °C and in a reducing or inert atmosphere, but preferably in a hydrogen atmosphere.
As the substrate cores such one can be employed which have already substantially the geometric form of the components to be finally manufactured such that they are allowed to be completely refrained from final shaping re-machining or merely minimum re-machining of the shape is correspondingly required.
However, with the solution according to the invention, substrate cores can also be employed in the form of porous semi-finished products having a preferably porous structure which one may denote as foam bodies as well.
In particular, with the production of such porous foam body structures the surface coating should be developed with a suspension/ dispersion which is made of the binding agent, metal powder and an additional solvent, as the case may be, or is made of a liquid.
Of course, it is also possible to deposit such suspensions/ dispersions upon non-porous substrate cores.
Such substrate cores having a porous structure are allowed to be fully immersed into such a suspension/ dispersion, and subsequently such a substrate core charged with suspension/ dispersion is allowed to be compressed in order to remove the suspension/ dispersion from the pores such that merely the webs remain wetted.
In the following, the stepped thermal treatment can then be carried out.
However, during the production of components in the form of porous foam bodies proceeding is also allowed to be such that a binding agent which has an appropriate viscosity by means of a solvent, as the case may be, will be employed for wetting the surfaces of the porous structure of such a substrate core wherein grouting can be also carried out herein for removing excess binding agent from the pores. Subsequently, the respective metal powder is then allowed to be deposited upon the wetted surfaces, wherein a more uniform distribution of the metal powder can be achieved by vibration. Subsequent to this, the stepped thermal treatment takes place then again.
It is also possible to deform substrate cores, preferentially such ones with a porous structure, after the development of surface coating and before the stepped thermal treatment.
Thus, for example, bending can be carried out under compliance of defined minimum bending radii. Thus, it is possible to manufacture hollow-cylinder shaped components or rather components shaped in a helical form.
With the solution according to the invention, however, it is also possible to readily manufacture composite members. On that occasion, proceeding is allowed to be such that at least one surface area of a substrate core will be provided with a surface coating as previously set forth.
Then, this surface area is allowed to be brought into touching contact with at least another substrate core, wherein on that occasion the adhesive effect of the binding agent can be used advantageously. Subsequent to this, the thermal treatment takes place during which a closure by adhesive force type connection of the respective substrate cores is then formed.
However, it is also possible to provide surface areas of two or several substrate cores to be connected together with closure by adhesive force with a surface coating and to bring those inro touching contact, and then to connect with closure by adhesive force by means of the thermal treatment. In this manner, composite members can be manufactured with complex geometries, which, for example, comprise undercuts or cavities, without shaping is required to occur subsequently.
However, it is also possible to manufacture composite members which are formed from a substrate core having a dense structure and a substrate core having a porous structure.
The metal powders to be employed according to the invention may also include preferably at least 50 wt% of carbon, molybdenum, iron, cobalt, niobium, titanium, aluminium, boron, zircon, manganese, silicon and/or lanthanum in addition to nickel having a minimum content of 20 wt%.
However, in addition to the respective powder composition, the properties of the components manufactured according to the invention can also be changed in that the surface coating will be developed in a different form on defined surface areas of substrate cores.
This relates to the respective thickness of the surface coating which can also be carried out by means of a repeated application in a different form, on the one hand, wherein a locally different consistency of the surface coating with different contents of metal powder, compositions of metal powder and granularity of metal powder can also be provided, on the other hand.
As a result, locally different properties on such a component manufactured according to the invention can be achieved.
With the solution according to the invention it is possible to manufacture components which comprise a graduated alloy composition starting from the surface. * Thus, for example, it is possible with the use of a substrate core made of pure nickel to manufacture a component which still has a core area of pure nickel after sintering, wherein the content of additional alloy elements changes/ increases successively towards the respective surfaces.
With the production of composite members as already mentioned, the graduated alloy compositions can also be developed in the joining area which has been formed by means of the closure by adhesive force type connections.
Components manufactured according to the invention have a higher ductility, creep resistance and strength compared with components which have been manufactured from nickel only, wherein this circumstance also applies in comparison with nickel aluminide.
The tendency of oxidation compared with nickel components can be reduced as well.
The components achieve a thermal stability of up to 1000 ° C, wherein components manufactured according to the invention with porous structures, in particular, present such extended possibilities of application themselves, which e. g. exclude the use of foams of nickel aluminide due to the brittleness thereof.
The components manufactured according to the invention, in particular, can be employed at higher dynamic loads.
