Description

  

  Verfahren zur Erzeugung von gegen gleitende Reibung     widerstandsfähigen        Oberflächen     bei     Naschinenteilen    aus     Aluminium    oder Aluminiumlegierungen.    Die Erfindung     betrifft    ein Verfahren zur  Erzeugung von gegen gleitende Reibung  widerstandsfähigen Oberflächen bei Maschinen  teilen, wie zum Beispiel Lagern, Gleitbahnen,  Führungen und dergleichen aus Aluminium  oder     Aluminiumlegierungen.     



  Dieses Verfahren ist dadurch gekenn  zeichnet, dass an den Oberflächen künstliche       Oxydschichten    erzeugt werden. Die Erzeu  gung solcher     Oxydschichten    kann insbesondere  durch Behandlung mit Wechselstrom in einem       elektrolytischen    Bade erfolgen.  



  Die Eignung dieser     Oxydschichten    zu  dem vorgenannten Zweck beruht auf ihrer  ausserordentlich grossen Härte. Diese Eignung  wird noch dadurch gesteigert, dass diese       Oxydschichten    ausserordentlich aufnahmefähig  für Fette, Öle, Schmiermaterialien usw. her  gestellt werden können und diese sehr fest  halten.  



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



  Process for producing surfaces that are resistant to sliding friction in machine parts made of aluminum or aluminum alloys. The invention relates to a method for producing surfaces resistant to sliding friction in machines parts, such as bearings, slideways, guides and the like made of aluminum or aluminum alloys.



  This process is characterized in that artificial oxide layers are created on the surfaces. Such oxide layers can be generated in particular by treatment with alternating current in an electrolytic bath.



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



  A running-in of the bearings for the purpose of "mirror" formation is therefore no longer necessary in such bearings made of aluminum or aluminum alloys with oxidized and oiled surfaces, and the risk of "seizing" is reduced to a minimum, or practically excluded.
