Description
Die Phosphorsäure li.it sowohl allein als auch in'Verbindung mit Metallen oder Metalloxyden bereits, vielfach Verwendung gefunden zur Erzeugung einer■ rostsicheren Schicht auf Eisen und Stahl.

In all of these known processes, the phosphoric acid is always in connection with only a single metal and metal oxide
*5 benutzt, die Schutzschicht besteht lediglich aus Eisenphosphat und einem anderen Aletallphosphat. Die bisherigen Verbesserungen und weiteren Ausgestaltungen des ursprünglichen, nur mit Phosphorsäure arbeitenden Verfahrens erschöpfen sich also in der Verstärkung der Eisenphosphatschicht durch ein -weiteres Metallphosphat.- Der Erfolg ist bedingt durch die besonderen Eigenschaften des gewählten Metalls bzw. Metalloxydes und beschränkt sich auf die rein äußerliche Verstär- kung der Eisenphosphätschicht durch eine weitere Schicht aus einem anderen Metall-' phosphat. Das innere Gefüge der Schutz-' schicht und ihre Verbindung .mit dem Eisen oder Stahl wird dadurch nicht verändert. 4o_* 5 used, the protective layer only exists from iron phosphate and another metal phosphate. The previous improvements and further developments of the original, Processes which only work with phosphoric acid are therefore exhausted in the reinforcement the iron phosphate layer by an additional metal phosphate. Success is conditional due to the special properties of the selected metal or metal oxide and is limited to the purely external reinforcement kung of the iron phosphate layer by a another layer of another metal ' phosphate. The inner structure of the protective layer and its connection with the iron or steel is not affected by it. 4o_

Gemäß <ler Erfindung werden zwei Metalle, insbesondere Kalzium und Zink,* mit einem Meialloxyd, wie Nickel, Kobalt, Mangan, Chrom o. dgl., zusammen mit Phosphorsäure angewendet. ! In contrast, strives for and achieves the finding a change in the protective layer in its internal composition and in their connection with iron or steel; she chooses from the large number of those who came before and, in some cases, already used substances for the same purpose and bring them to one very specific mutual influence on each other. According to the invention two metals, especially calcium and zinc, * with a metal oxide such as nickel, cobalt, Manganese, chromium or the like, used together with phosphoric acid. !

Man braucht sogar weder Kalzium noch Kalziumverbindungen zuzusetzen, wenn eine Phosphorsäure angewendet wird, deren Herstellung bereits den erforderlichen Kalkgehalt bedingt. An sich sind alle Arten Phosphorsäure verwendbar. Die Auswahl der jeweils am geeignetsten Art ist im wesentlichen eine Preisfrage. Im Bedarfsfalle wird die Phosphorsäure in Form ihrer. Salze angewendet.The Rpsts.chut ^ sä.iifCj'b ^ must not have any immediate Addition of calcium, but potassium compounds of where · calcium phosphate is most suitable has proven. You don't even need to add calcium or calcium compounds, if a phosphoric acid is used, its production already has the necessary Limestone content conditional. All types of phosphoric acid can be used per se. The selection the most suitable type in each case is essentially a question of price. If necessary the phosphoric acid is in the form of its. Salts applied.
Ein Ausführungsbeispiel des Verfahrens ist folgendes: /An embodiment of the method is the following: /
In ι 1 Phosphorsäure, welche 10 bis 20 Prozent phosphorsauren Kalk enthält, werden 100 g Zink aufgelöst. Die konzentrierte Lösung wird mit 100 1 Wasser und 300 g Manganoxyd versetzt. Das derart hergestellte Bad, welches zuvor auf Kochtemperatur gebracht ist, nimmt die metallisch reinen Eisenteile auf, welche nach etwa zwei Stunden mit einer rostsichcren Schutzschicht bedeckt sind. Das Mengenverhältnis der einzelnen Bestandteile wechselt naturgemäß entsprechend dem jeweiligen Venvendungsgebiet ■ des Verfahrens. In ι 1 phosphoric acid, which is 10 to 20 percent Contains phosphoric acid lime, 100 g of zinc are dissolved. 100 l of water and 300 g of manganese oxide are added to the concentrated solution. The manufactured in this way The bath, which has been brought to boiling temperature beforehand, absorbs the metallically pure iron parts, which with it after about two hours are covered with a rust-proof protective layer. The proportions of the individual components naturally changes according to the respective area of ■ use of the procedure.
Praktische Versuche haben ergeben, daß eiserne Gegenstände, welche nach den bekannten Verfahren behandelt sind, bereits nach einigen Tagen starke Rostspuren zeigen, welche sich immer mehr verstärken und nach i4tägiger Lagerung zur vollständigen Rostbildung neigen. Von den gemäß der Erfindung behandelten Gegenständen zeigen dagegen nur einige vereinzelteRostflecken, selbst ; wenn sie 14 Tage lang dem> stärksten Regen ausgesetzt sind. Die Rostflepken beeinträchtigen die Rostschutzschicht nicht im geringsten, verschwinden vielmehr beim Abbürsten vollkommen. .Practical tests have shown that iron objects which have been treated according to the known processes show strong traces of rust after a few days, which become increasingly stronger and tend to rust completely after storage for 14 days. On the other hand, only a few of the objects treated according to the invention show isolated rust spots themselves ; if they are exposed to> the heaviest rain for 14 days. The rust spots do not affect the rust protection layer in the slightest, but rather disappear completely when brushed off. .
