Description
Es ist bereits mehrfach vorgeschlagen worden, Spulen für die Zwecke der Hochfrequenztechnik mit Eisenkernen zu versehen, welche aus fein unterteiltem Eisenpulver, gegebenenfalls in Vermischung mit einem Isoliermaterial, bestehen.It has already been proposed several times, coils for the purposes of high-frequency technology to be provided with iron cores, which are made of finely divided iron powder, if necessary mixed with an insulating material.
Die vorliegende Erfindung bezieht sich auf eine besondere Herstellungsart solcher magnetischer Spulenkörper. Sie besteht in einer; The present invention relates to a particular type of manufacture of such magnetic bobbins. It consists of one;
to über das bisher bekannte Maß hinausgetriebenen Unterteilung eines Materials mit höherer Permeabilität als Luft, insbesondere von Eisen, Nickel, Kobalt oder Häuslersche Legierung, und zwar erfolgt die Unterteilung durch die Benutzung eines Zerstäubungsverfahrens, wie das bekannte Metallzerstäubungsverfahren, bei welchem das Metall geschmolzen und unter starkem Druck fast in seine Moleküle aufgelöst und dann wieder nieder-to be driven beyond what was previously known Subdivision of a material with higher permeability than air, in particular of iron, nickel, cobalt or Häusler's alloy, and the subdivision is made by using an atomization process, such as the well-known metal atomization process, in which the metal melted and almost dissolved into its molecules under strong pressure and then
ao geschlagen wird, oder des Verfahrens der kathodischen Zerstäubung in Gasen oder Flüssigkeiten oder Benutzung der Elektrolyse. Es können auf diese Weise nicht nur reguläre Schichten. erzeugt werden, bei denen magnetische und nichtmagnetische bzw. isolierende Schichten abwechseln, sondern es können auch völlige Mischungen hergestellt werden, so daß fast eine molekulare Zerteilung des Magnetikums entsteht, wobei dei» leitende Zusammenhang der magnetischen Moleküle fast oder nahezu vollständig unterbrochen ist.ao is beaten, or the process of cathodic sputtering in gases or liquids or using electrolysis. Not only regular shifts can do it this way. are generated in which magnetic alternate with non-magnetic or insulating layers, but complete mixtures can also be produced, so that there is almost a molecular division of the magnetic, whereby the conductive connection of the magnetic molecules is almost or almost completely interrupted.
Es ist klar, daß bei einer so weit getriebenen Unterteilung Verluste durch Wirbelströme in einem bisher unerreichbaren Maße unterdrückt werden können. Man hat den λ''orteil, daß Beimengungen zu dem Eisen, welche dessen Leitfähigkeit herabsetzen, fortgelassen werden können, obgleich es natürlich auch unbenommen ist, diese Beimengungen beizubehalten. Man gewinnt ;durch; .das Verfahren vor . allen Dingen den Vorteil, daß die beim W'alzen auftretende unvermeidliche Strukturänderung an der Oberfläche, welche die Herstellung dünnerer Bleche als etwa 1Z300 mm verhindert und auch magnetisch bekanntlich sehr nachteilige Folgen hat, fortfällt. Eine Ausführungsform des Erfindungsgedankens sei eingehender beschrieben. It is clear that with a subdivision that has been carried out so far, losses due to eddy currents can be suppressed to a previously unattainable degree. One has the advantage that admixtures to the iron, which reduce its conductivity, can be omitted, although it is of course also at liberty to retain these admixtures. One wins; through; .procedure the procedure. All things have the advantage that the unavoidable structural change on the surface which occurs during rolling, which prevents the production of sheets thinner than about 1 × 300 mm and which is also known to have very disadvantageous magnetic consequences, is eliminated. An embodiment of the inventive concept will be described in more detail.
Mittels einer gewöhnlichen Metallzerstäu=- bungsvorrichtung wird Eisen erst auf eine Unterlage, z. B. aus Papier, in Form einer äußerst dünnen Schicht zerstäubt. Die so entstandene Schicht wird z. B. lackiert, auf die Lackschicht wird wiederum eine Eisen-Schicht aufgestäubt, diese wiederum lackiert und so fort, bis man ein Blech oder eine Platte von beliebiger Dicke hergestellt hat. Die Festigkeit des so entstandenen Magnetikums ist recht beträchtlich und gestattet ohne Beeinträchtigung der magnetischen Eigenschaften die Bearbeitung mit den gewöhnlichen Arbeitsmethoden, wie Fräsen, Schleifen, Bohren, Drehen usw. Die magnetische Leitfähigkeit dieses Materials ist zwar im allgemeinen nicht so hoch wie die der bisher ge-By means of an ordinary metal atomization = - Exercise device is iron only on a pad, z. B. made of paper, in the form of a extremely thin layer atomized. The resulting layer is z. B. painted on the lacquer layer is in turn dusted with an iron layer, which in turn is lacquered and so on, until a sheet or plate of any thickness has been made. The strength of the magnetic material created in this way is quite considerable and is permitted without Deterioration of the magnetic properties machining with the ordinary Working methods such as milling, grinding, drilling, turning, etc. The magnetic The conductivity of this material is generally not as high as that of the previously used
L·L
bräuchlichen Bleche, jedoch beträgt sie immerhin noch erheblich mehr als die Leitfähigkeit der Luft. '" ' ' 'common sheet metal, but it is still considerably more than the conductivity the air. '"' ''
Mit einer geringen .Abänderung kann man dem Magnetikum ganz beliebige Formen geben. Man kann z. B. eine Spule vollständig in dieser Weise mit magnetisch leitfähigem Material umgeben und den Innenraum ausfüllen. Man kann auch, statt abwechselnderWith a slight change you can give the Magnetikum any shape. You can z. B. a coil completely Surrounded in this way with magnetically conductive material and fill the interior. One can also, instead of alternating
ίο schichtweiser Herstellung von magnetisch leitfähigen und isolierenden Schichten eine unmittelbare Vermengung eintreten lassen, wenn man z. B. gleichzeitig Eisen und Glas zerstäubt und eine völlige (Durchmisehung dieser beiden Substanzen eintreten läßt. ίο layer-by-layer production of magnetically conductive and insulating layers allow a direct amalgamation occur if you z. B. simultaneously atomized iron and glass and allows a complete (Durchmisehung of these two substances to occur .
In ähnlicher Weise ist die kathodische Zerstäubung verwendbar, oder ein elektrolytisches \f erfahren, bei welchem »z.B. mittels Lichtbogen ■köMeida+e-ises'tmgen von Eisen hergestellt werden, welche elektrolytisch niedergeschlagen werden. Hier kann man besonders leicht schichtweise Oxydation eintreten lassen welche den leitfähigen Zusammenhang der einzelnen niedergeschlagenen -Schichten ganz oder teilweise aufhebt. Cathodic sputtering can be used in a similar way, or an electrolytic process in which iron is produced, for example by means of an electric arc, which is then deposited electrolytically. Here it is particularly easy to let oxidation occur layer by layer, which completely or partially removes the conductive connection between the individual deposited layers.
Für viele Zwecke ist es geeignet, auf diese Weise massive Platten herzustellen, aus denen die gewünschten Formen herausgearbeitet werden', z. B. Formkörper für Hochfrequenzmaschinen, Körper für Transformatoren, Spulen, Variometer u.dgl. Für andere Zwecke ist, es vorteilhaft, Bleche von der Dicke bis zu ι mm herzustellen, die man aufeinander schichtet und ähnlich wie das bisher gebräuchliche Transformatorenblech weiter verwendet. It is suitable for many purposes to produce massive plates from which the desired shapes worked out become ', e.g. B. Shaped bodies for high-frequency machines, bodies for transformers, Coils, variometers, etc. For other purposes, it is advantageous to use sheets of up to to produce ι mm, which are stacked on top of each other and similar to what has been used up to now Transformer sheet continues to be used.
