  Verfahren zur Erzeugung von gegen gleitende Reibung widerstandsfähigen Oberflächen an Lagern,
Gleitbahnen, Führungen u. dgl. aus Aluminium oder Aluminiumlegierungen. 



   Die Erfindung betrifft ein Verfahren zur Erzeugung von gegen gleitende Reibung widerstandsfähigen Oberflächen an Lagern, Gleitbahnen, Führungen u. dgl. aus Aluminium oder Aluminiumlegierungen. 



   Dieses Verfahren besteht darin, dass an den Oberflächen in an sich bekannter Weise künstliche Oxydschichten erzeugt werden. Insbesondere eignet sieh dazu die bekannte Behandlung mit Wechselstrom in einem elektrolytischen Bade. 



   Die Eignung dieser Schichten zu dem vorgenannten Zweck beruht auf ihrer ausserordentlich grossen Härte. Diese Eignung wird noch gesteigert durch die Erkenntnis, dass diese Oxydschichten ausserordentlich aufnahmefähig für Fette, Öle,   Sehmiermaterialien   usw. sind und diese sehr festhalten. 



   Ein Einlaufen der Lager zum Zwecke der Spiegel-Bildung ist daher bei solchen Lagern aus Aluminium mit oxydierter und eingeölter Oberfläche nicht mehr nötig   :   ferner ist die   Gefahr des Fressens"   auf ein Mindestmass herabgesetzt bzw. praktisch ausgeschlossen. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Erzeugung von gegen gleitende Reibung widerstandsfähigen Oberflächen bei Lagern, Gleitbahnen, Führungen u. dgl. aus Aluminium oder Aluminiumlegierungen, dadurch gekennzeichnet, dass dieselben mit einer nach bekannten Verfahren, z. B. durch   Weehselstrombehandlung,   erzeugten Oxydhaut versehen werden.

  Process for producing surfaces on bearings that are resistant to sliding friction,
Slideways, guides, etc. Like. Made of aluminum or aluminum alloys.



   The invention relates to a method for producing surfaces on bearings, slideways, guides and the like that are resistant to sliding friction. Like. Made of aluminum or aluminum alloys.



   This method consists in creating artificial oxide layers on the surfaces in a manner known per se. The known treatment with alternating current in an electrolytic bath is particularly suitable for this purpose.



   The suitability of these layers for the aforementioned purpose is based on their extraordinarily great hardness. This suitability is further increased by the knowledge that these oxide layers are extremely absorbent for fats, oils, absorbent materials, etc. and hold them very firmly.



   Running-in of the bearings for the purpose of mirror formation is therefore no longer necessary in such bearings made of aluminum with an oxidized and oiled surface.



   PATENT CLAIMS:
1. Process for the production of surfaces resistant to sliding friction in bearings, slideways, guides and the like. Like. Made of aluminum or aluminum alloys, characterized in that the same with a known method, for. B. by Weehselstrom treatment, generated oxide skin are provided.
