Description
Verfahren zum Einlagern von organischen oder anorganischen Stoffen in anodisch erzeugten Oxydschichten auf Aluminium und Aluminiumlegierungen Gegenstand der Erfindung ist ein Verfahren zum Einlagern von organischen oder anorganischen Stoffen. insbesondere gummi- oder harzartigen, in anodisch erzeugten Oxydschichten auf Aluminium oder Aluminiumlegierungen.Process for storing organic or inorganic substances in anodically generated oxide layers on aluminum and aluminum alloys the invention is a method for incorporation of organic or inorganic Fabrics. in particular rubber or resin-like, in anodically generated oxide layers on aluminum or aluminum alloys.
Das Tränken oder Streichen anodisch erzeugter OYvdschichten mit Ölen oder Fetten sowie das Graphitieren derselben ist bekannt. Ebenfalls bekannt ist der Zusatz von Pflanzenstoffen zum Elektrolyt zur Badabdeckung, Erhöhung der Streufähigkeit des Elektrolyt oder zur Verbesserung der Anfärbbarkeit. Das neue Verfahren besteht darin, daß man bereits dem Elektrolyt, die zur Verankerung mit der .Metalloberfläche vorgesehenen organischen oder anorganischen Stoffe in einer Menge von o,5 bis 5 °!o zusetzt und die so vorbereitete Oxydschicht mit einer Lösung nachbehandelt, die in beliebiger Konzentration die gleichen oder gleichartigen Zusatzstoffe enthält.Soaking or painting anodically produced OYvdschichten with oils or greasing and graphitizing the same is known. Is also known the addition of plant substances to the electrolyte to cover the bath, increasing the throwing power of the electrolyte or to improve the colorability. The new procedure exists in that you already have the electrolyte, which is used for anchoring with the .Metalloberfläche intended organic or inorganic substances in an amount of 0.5 to 5 °! O is added and the oxide layer prepared in this way is treated with a solution, which contains the same or similar additives in any concentration.
Die Behandlung nach der Erfindung liefert sehr viel bessere Ergebnisse als die bisher bekannten Verfahren zur Erzeugung von gleit- und abriebbeständigen Notlaufschichten auf Aluminim und aufm Aluminiumlegierungen. Mit Hilfe des 'Verfahrens wird es beispielsweise möglich, daß in Feinpassung zusammengebaute und gegeneinander bewegte Maschinenteile - aus . der gleichen Aluminiumlegierung hergestellt. werden können. Des weiteren wirddie Bindung von Leichtmetall mit .The treatment according to the invention gives much better results than the previously known methods for producing slip and abrasion resistant Emergency running layers on aluminum and on aluminum alloys. With With the help of the 'method it is possible, for example, to fit together with a fine fit and machine parts moving against each other - from. the same aluminum alloy manufactured. can be. Furthermore, the binding of light metal with.
-gummi--Yflderi-harzartigen Werkstoffen wesentlich erleichtert und verbessert.-gummi - Yflderi-resinous materials significantly facilitated and improved.
Den während der Elektrolyse bis zum Grunde der Oxydschicht eingelagerten, die Schichtstruktur mitbestimmenden Stoffen gesellen sich bei der anschließenden Nachbehandlung mit gleichartigen Stoffen diese inniger bei, als dies bei einer nicht verfahrensgemäßen Behandlung möglich ist.The deposited during the electrolysis to the bottom of the oxide layer, the layer structure co-determining substances join the subsequent one Post-treatment with similar substances does this more intimately than one does not procedural treatment is possible.
Die Stärke der Oxydschicht kann vorteilhaft beeinflußt werden, wenn dem Elektrolyt Gerbstoffe in einer Menge von 25 bis 3,o Gewichtsprozent der Zusatzstoffe zugesetzt werden.The thickness of the oxide layer can be influenced advantageously, if the electrolyte tannins in an amount of 25 to 3.0 percent by weight of the additives can be added.
Um eine besonders gute Verankerung mitgummi-oder harzartigen Stoffen zu ermöglichen, ist eine möglichst große Schichtstärke der Oxydschicht er-@vünscht. Anwendungsbeispiel i Bildung einer Notlaufschicht auf Getriebeteilen: Elektrolyt 2oo/oige H2 S04, Behandlungstemperatur 30°; Stromspannung .15 Volt, Behandlungsdauer 50 Minuten: Zusatz zum Elektrolyt: ,1,2 Gewichts-Prozent Harzstoffe, 0,3 % Gerbstoffe. Nachbehandlung: . etwa 25o/oige Harzstöfflösung gleicher Art wie das Zusatzmittel, Temperatur 95°, Behandlungsdauer 2o Minuten.In order to enable particularly good anchoring with rubber or resin-like substances, the greatest possible layer thickness of the oxide layer is desired. Application example i Formation of an emergency running layer on gear parts: electrolyte 2oo / o H2 S04, treatment temperature 30 °; Voltage .15 volts, treatment time 50 minutes: Additive to the electrolyte:, 1.2 percent by weight resin substances, 0.3% tannins. Follow-up treatment:. About 25% resin solution of the same type as the additive, temperature 95 °, treatment time 20 minutes.
Anwendungsbeispiel a Erzeugung einer Schicht für Leichtmetall-Gummi-Bindung: Elektrolyt und Elektrolyse wie in Beispiel i. Zusatz zum Elektrolyt: ,2% Gummiemulsion, Nachbehandlung mit Gummilösung und Aufvulkanisieren der Gummischicht.Application example a Creation of a layer for a light metal-rubber bond: Electrolyte and electrolysis as in example i. Additive to the electrolyte:, 2% rubber emulsion, Post-treatment with rubber solution and vulcanization of the rubber layer.
Die Konzentration der Nachbehandlungslösung, die Nachbehandlungsdauer und die Temperatur können beliebig gewählt werden und richten sich nach der Art des Einlagerungsstoffes.The concentration of the post-treatment solution, the post-treatment duration and the temperature can be chosen arbitrarily and depend on the type of the storage material.
Auch die Art des Elektrolyts ist unwichtig. Es kann jeder Elektrolyt zur Anwendung kommen, der sieh zur Oxydation von Aluminiumlegierungen eignet.The type of electrolyte is also unimportant. Any electrolyte can do it are used, which see suitable for the oxidation of aluminum alloys.
