Description

Verfahren zur Herstellung von Kupfer-Phosphor-Legierungen Die Kupfer-Phosphor-Legierungen werden durch Zugabe von elementarem gelbem Phosphor zu hocherhitztem Kupfer hergestellt. Sie enthalten 5 bis zio% Phosphor und dienen zum Ausphosphorn von Bronze bis zu einem Gehalt von etwa o,2% Phosphor.Process for the production of copper-phosphorus alloys The copper-phosphorus alloys are made by adding elemental yellow phosphorus to highly heated copper. They contain 5 to zio% phosphorus and are used to ausphosphorn from bronze up to a content of about 0.2% phosphorus.

Das geschilderte Herstellungsverfahren hat folgende Nachteile: Elementarer Phosphor ist sehr teuer, und die Handhabung mit diesem äußerst giftigen Stoff ist mit großen Gefahren verbunden.The manufacturing process described has the following disadvantages: More elementary Phosphorus is very expensive and handling of this extremely toxic substance is associated with great dangers.

Durch die Erfindung werden diese Nachteile beseitigt. Das Verfahren ist sehr wirtschaftlich und, da elementarer Phosphor auch als Zwischenprodukt nicht auftritt, völlig ungefährlich. Es besteht darin, feinverteiltes Kupfer in Form von Pulver oder Spänen mit gepulvertem Ammonphosphat zu mischen und diese Mischung unter reduzierenden Bedingungen zu erhitzen, wobei sich schon bei 400 bis 6oo° Kupfer-Phosphor-Legierungen bilden. Zur Reduktion benutzt man Wasserstoff, Wassergas, Ferngas oder auch feinverteilte Kohle. Das Verfahren sei an folgendem Beispiel beschrieben: Zur Herstellung einer io0/aigen:Kupfer-Phosphor-Legierung gibt man zu ioo Teilen Kupferpulver .42 Teile (N H4)2 H P O4. Die Mischung wird unter reduzierendem Gas, z. B. Leuchtgas, erhitzt. Bei etwa 13o° tritt der gesamte Ammoniak aus. Nach Überschreiten der Temperatur von etwa 38a° beginnt die Reduktion. Sie ist bei 5oo° nach kurzer Zeit beendet.The invention overcomes these disadvantages. The procedure is very economical and, since elemental phosphorus is also not an intermediate product occurs, completely harmless. It consists in finely divided copper in the form of Mix powder or shavings with powdered ammonium phosphate and add this mixture reducing conditions to heat, with copper-phosphorus alloys already at 400 to 6oo ° form. Hydrogen, water gas, long-distance gas or finely divided gas is used for the reduction Money. The process is described using the following example: To produce a io0 / aigen: Copper-phosphorus alloy is added to 100 parts of copper powder .42 parts (N H4) 2 H P O4. The mixture is under reducing gas, e.g. B. luminous gas, heated. At about 130 ° all of the ammonia escapes. After exceeding the temperature from about 38 ° the reduction begins. It ends after a short time at 500 °.

Für die Herstellung von Gegenständen auf pulvermetallurgischem Weg, z. B. gewalzten Bändern aus Phosphor-Bronze, mischt man das Ammoniumphosphat dem Metallpulver zu. Man walzt die Bänder nach bekannten Verfahren. Bei der Glühung wird das Phosphat leicht reduziert, und man erhält auf diese Weise die gewünschte Auf phosphorung.For the manufacture of objects using powder metallurgy, z. B. rolled strips of phosphor bronze, you mix the ammonium phosphate Metal powder too. The strips are rolled using known processes. During the annealing the phosphate is slightly reduced, and one gets that way the desired phosphor coating.

Der technische Fortschritt des Verfahrens ist durch die Anwendung des billigen, als Düngemittel im großtechnischen Maßstab zur Verfügung stehendenn Ammoniumphosphates und weiter durch die einfache Arbeitsweise gegeben.The technical progress of the process is due to the application of the cheap, available as fertilizer on an industrial scale Ammonium phosphates and on given by the simple way of working.
