Zusatz zum Patent 284911.Addendum to patent 284911.
Patentiert im Deutschen Reiche vom 31. Januar 1915 ab. Längste Dauer: 11.August 1928.Patented in the German Empire on January 31, 1915. Longest duration: August 11, 1928.
In dem Patent 284911 ist ein Verfahren zum Schütze von dampfförmigen Metallen vor Oxydation bei Ausübung des bekannten Spritzverfahrens beschrieben, bei welchem der Zerstäubungsstrahl mit einem Mantel aus indifferenten Gasen umkleidet wird. Die vorliegende Erfindung verwendet ebenfalls die Idee, indifferente Gase als Schutzmantel gegen Oxydation bei Ausübung des Uberzugsverfahrens zu verwenden. Sie besteht darin, daß das indifferente Gas in ständigem Strom durch einen Behälter hindurchgeführt wird, in welchem der zu überziehende Gegenstand behandelt wird. Es ist' bereits bekannt, zur Herstellung von metallreinem Bronzepulver flüssiges Metall durch Bestrahlung mit Wasserstöffgas oder einem anderen sauerstoffreinen Gas in einer sauerstofffreien Kammer zu zerstäuben. Ebenso ist es bereits bei Ausübung desIn patent 284911 is a method for the protection of vaporous metals from oxidation when practicing the known spraying process, in which the atomizing jet is covered with a coat of inert gases. The present Invention also uses the idea of inert gases as a protective jacket against oxidation to be used when exercising the overdraft procedure. It consists in the indifferent Gas is passed in a constant stream through a container in which the the object to be coated is treated. It is' already known for the production of pure metal bronze powder liquid metal by irradiation with hydrogen gas or atomizing another oxygen-free gas in an oxygen-free chamber. It is the same when exercising the
ao unter der Bezeichnung »Sherardisieren« bekannten Niederschlagyerfahrens vorgeschlagen worden, geschlossene Behälter zu verwenden. ao proposed precipitation method known as "Sherardizing" been to use closed containers.
Auf der Zeichnung ist eine im Sinne der Erfindung wirkende Einrichtung schematisch dargestellt. In the drawing, a device acting in accordance with the invention is shown schematically.
In den Behälter α mündet bei b die Düse, durch welche die heißen Metalldämpfe in den Behälter eintreten, c ist eine beispielsweise mit Kohlensäure gefüllte Flasche, die durch die Leitung d ihren Inhalt in das Innere des Behälters α ausströmen lassen kann. Oben und unten sind an dem Behälter Ableitungen e bzw. f vorgesehen, die beide in eine Vorlage g münden, die beispielsweise mit Wasser gefüllt ist. In der Wandung des Behälters sind ferner Öffnungen h vorgesehen, die zum Einbringen der Arme in das Innere des Behälters und somit zum Einführen des zu behandelnden Werkstückes vor die Düse dienen. Um dabei den Arbeitsvorgang beobachten zu können, ist bei i ein Fenster in der Wandung des Behälters α vorgesehen. The nozzle through which the hot metal vapors enter the container opens into the container α at b , c is a bottle filled, for example, with carbonic acid, which can let its contents flow out through the line d into the interior of the container α. At the top and bottom of the container there are outlets e and f , which both open into a template g , which is filled with water, for example. In the wall of the container openings h are also provided, which serve to introduce the arms into the interior of the container and thus to introduce the workpiece to be treated in front of the nozzle. In order to be able to observe the work process, a window is provided in the wall of the container α at i .
Die bei b einströmenden Metalldämpfe befinden sich dauernd unter dem Einfluß der durch d einströmenden indifferenten Gase, welche die etwa in dem Behälter vorhandene atmosphärische Luft verdrängen und im weiteren Verlauf der Behandlung den Zutritt von Luft verhindern. Die verbrauchten indifferenten Gase sowie die verdrängte atmosphärische Luft und die sich niederschlagenden unverbrauchten Metalldampf teile gelangen je nach ihrer spezifischen Schwere entweder durch die obere Ableitung e oder die untere f in die Vorlage g. The metal vapors flowing in at b are constantly under the influence of the inert gases flowing in through d , which displace any atmospheric air present in the container and prevent the entry of air in the further course of the treatment. The used indifferent gases as well as the displaced atmospheric air and the precipitating unused metal vapor parts, depending on their specific gravity, pass either through the upper discharge line e or the lower line f into the template g.
