Description
tates 8 Claims ABSTRACT OF THE DISCLOSURE A process for the production of compact, malleable and rollable metal workpieces from dispersion-hardened starting materials. Compact, malleable and rollable workpieces are prepared by the electrodeposition of a metal component onto a metal carrier such as a wire or sheet, the dimensions of the carrier being small in relation to the volume of deposited metal, there being added to the deposition bath a refractory material and a wetting agent.
BACKGROUND OF THE INVENTION In known processes for the manufacture of compact, malleable and rollable metal workpieces from dispersionhardened materials in accordance with the techniques of powder metallurgy, there is the drawback that, despite subsequent heat treatment, the dispersed material frequently deposits at the grain boundaries of the former metal powder particles, whereas the main disadvantage of Working materials produced by internal oxidation or reduction lies in the frequent microscopic and macroscopic nonuniformity of subdivision of the dispersed material. This has as a consequence that the desired dispersion hardening effect is insufiiciently attained. It is an object of the invention to avoid the disadvantage of these known methods.
SUMMARY OF THE INVENTION In accordance with the present invention, workpieces which are compact, malleable and rollable are produced electrolytically from dispersion-hardened materials, by depositing a metallic component, such as a pure metal or an alloy, from an electrolyte, upon a suitable carrier, such as a sheet or wire, While simultaneously introducing a refractory component; advantageously, a suitable wetting or dispersing agent is also added to the electrolyte.
The metallic component may be any desired metal or alloy. Examples of metal which may be used to advantage in the practice of the invention include nickel, co-
balt, columbium, vanadium, silver, and lead, while examples of suitable alloys include alloys of nickel and cobalt, containing from 10% to 50%- cobalt, or alloys of nickel and molybdenum containing from to 25% molybdenum, as well as also alloys of cobalt with nickel and tungsten, alloys of nickel with cobalt, molybdenum, tungsten and chromium, and alloys of columbium with titanium, molybdenum, tungsten and zirconium.
Refractory materials which may be employed in accordance with the invention include the oxides, carbides, nitrides, and borides of metals such as aluminum, thorium, cadmium, titanium and zirconium, or mixtures thereof. Examples include A1 0 ThO TiB and ZrC. The proportion of such refractory material to the metal component is from about 0.5% to about by weight.
As a carrier material upon which the metal component is deposited, there may be employed metal wire, sheet,
or shapes, having such small dimensions, e.g., cross section and thickness, that the carrier volume is small relative to the deposited volume of the metal component, e.g., 22% by volume. The carrier material is preferably identical with the metal to be deposited, or in the case of alloys, with the main component of the alloy.
Advantageously, there may be added to the electrolyte a suitable wetting or dispersing agent, in an amount ranging from about 0.01% to about 0.5% by weight of the bath. Examples of suitable classes and types of wetting agents include: P18 of Langbein-Pfanhauser, AG 4 of Harshaw Chemicals Ltd., Manoxol of Hardmann & Holden Ltd., Empicol of Marchon Products Ltd.
These wetting agents are typically sulfates of normal primary aliphatic alcohols containing from 8 to 18 carbon atoms, such as Empicol, or sodium salts of 2- ethylhexylsulfate or 2-ethylhexylsulfonate, or they are sodium salts of dioctyl sulfosuccinic acid, such as Manoxol. Preferably the wetting agent is added to the electrolyte continuously during the deposition.
Furthermore, the refractory material in the form of a powder is also added to the electrolyte, whereby the refractory material remains uniformly distributed throughout the electrolyte in consequence of movement of the electrolyte. Pore formation in the workpiece is best prevented by mechancal means, such as, for example, by suspending the carrier material in an electromagnetic vibrator, which is set in vibration during the deposition of the metal. Another means consists in subjecting the workpiece periodically to a blow during the deposition of the metal, for example, by means of an electromagnet.
To achieve the desired properties, the workpiece, after the electrolytic deposition, is compacted by extrusion, o1 forging, or explosive molding.
Typical electrolyte compositions which may be employed in the practice of the invention are as follows:
(a) 256 g. NiSO .7H O; 45 g. NiCl .6H O; 30 g.
H3BO3 per 1 H20 (b) 300 g. PbCO 60 g. HBF g. H BO per 1 H 0 (0) 0.05 mol C080,; 0.15 mol ammonium tungstate; 0.2 mol Na 'C H 0.1 mol (NH SO and 2.5 mol NH per 1 H O.
The advantage of the novel method of the invention compared to previously known methods is especially evident in the very even distribution of the dispersed materials in the individual grains of the product.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The following example illustrates the practice of the invention, but is not to be regarded as limiting:
Example I As the electrolyte there was employed a conventional nickel deposition bath having the following composition:
256 g. NiSO .7H O; 45 g. NiCl .6H O; g. H BO per 1 H O To this bath there was continuously added as a wetting agent the compound P18 of Langbein-Pfanhauser, in an amount constituting about 0.04% by weight of the bath. As the refractory material there was introduced into the bath aluminum oxide having a particle size of less than 2 ,um, in a concentration of 80 g./l. of electrolyte, taking care that the aluminum oxide was uniformly distributed in the bath during the electrolytic deposition of the dispersionhardened alloys, e.g., rod material having a diameter of mm. Pore formation by gas bubbles in the workpiece was prevented by mechanical means, namely, by electromagnetically vibrating the carrier material during deposition. The anode was a massive nickel anode, well known in the plating art, or alternatively, small nickel pieces contained in titanium jackets. The carrier upon which deposition of the nickel took place was a formed wire of nickel, having a small cross section, so that its volume in relation to the total deposited volume would be small and would not influence the properties of the finished workpiece. Wire of 1 mm. diameter was used. The nickel was deposited to a diameter of 50 mm. Thus, the volume of the carrier wire is V2500 that of the finished workpiece. The electrolysis was performed at a temperature of 40 C., voltage of 1-3, and current density of 0.06 a./cm.
The product was compressed in an extrusion press. The compacted workpiece was malleable and rollable and suitable for further processing.
The workpieces produced in accordance with the novel method of the invention can be used in a wide variety of applications by reason of the wide range of properties which can be imparted to them according to their composition. Thus, for example, the workpiece prepared from nickel and aluminum oxide, as illustrated in Example I above, exhibits a high degree of heat resistance and at the same time an enhanced resistance to wear and abrasion, so that it is particularly well suited for turbine blades, parts of combustion chambers and jet engines. A workpiece made from silver with refractory components is very useful for electrical contacts.
It will be understood that the above description of the present invention is susceptible to various modifications, changes and adaptations, and the same are intended to be comprehended within the meaning and range of equivalents of the appended claims.
We claim:
