die aus dem Metallbad gekommenen Gegenstände.the objects that came out of the metal bath.
Patentiert im Deutschen Reiche vom 10. Februar 1910 ab.Patented in the German Empire on February 10, 1910.
Die Erfindung betrifft ein Verfahren zur Erzielung eines festhaftenden dichten und gleichmäßigen Metallüberzuges auf Metallkörpern. The invention relates to a method for achieving a tightly adhering and tight even metal coating on metal bodies.
Bei den bisher bekannten Verfahren sind die Gegenstände entweder auf elektrolytischem Wege überzogen, oder sie sind in ein flüssiges Metallbad getaucht und dann abgekühlt. Nach dem amerikanischen Patent 494668 werden die Gegenstände nach dem Verlassen des feurig flüssigen Metallbades durch Walzen gezogen, um das überflüssige Metall zu entfernen und das haftende fest anzupressen. Nach den deutschen Patentschriften 63010 und 113872 werden die Gegenstände nach dem Verlassen des Metallbades einem heißen kräftigen Luftstrom ausgesetzt, um durch diesen das überflüssige Metall abzublasen.In the previously known methods, the objects are either electrolytic Paths coated, or they are immersed in a liquid metal bath and then cooled. According to the American patent 494668, the objects are after leaving the fiery liquid metal bath pulled through rollers to remove the excess metal and firmly press on the adhesive. According to German patents 63010 and 113872 the objects become a hot vigorous after leaving the metal bath Exposed to a stream of air in order to blow off the excess metal through it.
Bei vorliegendem Verfahren werden die Gegenstände nach dem Verlassen des feurig flüssigen Metallbades in einer verschließbaren Bombe dem statischen Drucke eines heißen indifferenten Gases ausgesetzt, durch welchen das flüssige Überzugsmetall fest an das Grundmetall gepreßt und durch die Schwerkraft das überflüssige Metall zum Abtropfen gebracht wird.In the present method, the objects become fiery after leaving the liquid metal bath in a sealable bomb to the static pressure of a hot exposed to indifferent gas, through which the liquid coating metal firmly to the base metal pressed and caused by gravity to drain the excess metal will.
Gegenüber dem Verfahren nach dem amerikanischen Patente wird erreicht, daß Gegenstände jeglicher Form dem Verfahren unterworfen werden können und der Überzug einem andauernden Drucke an jeder Oberflächenstelle gleichmäßig ausgesetzt ist und das überflüssige Metall auf natürlichem Wege durch Hitze und Schwerkraft entfernt wird, während gegenüber den deutschen Patenten 63010 und 113872 die flüssigen Überzugsmetalle indifferenten Gasen ausgesetzt werden, wodurch jegliche Oxydation vermieden wird und auch ein gleichmäßiger Druck auf die ganze Oberfläche ausgeübt wird, wodurch das Überzugsmetall fest an den Grundkörper gepreßt und eine bessere Haltbarkeit des Überzuges erreicht wird.Compared to the method according to the American patents it is achieved that objects any shape can be subjected to the process and the coating can be subjected to continuous printing at any surface location is evenly exposed and the excess metal naturally through heat and gravity is removed, while over against German patents 63010 and 113872 the liquid coating metals are exposed to inert gases, whereby any Oxidation is avoided and also an even pressure on the whole surface is exercised, whereby the coating metal is pressed firmly to the base body and a better durability of the coating is achieved.
