Description

  

      Verfahren        zum        Aufbringen    von     Metallverbindungen    auf feste Körper    Um an feste Körper     Metallverbindungen    anzu  lagern, verfährt man bislang in der Weise, dass     man     diese entweder chemisch, elektrolytisch oder mecha  nisch, z. B. durch     Walzen,    Prägen oder in anderer  Weise, unter Druck     aufbringt.    Diesen Verfahren  haften Nachteile an, wie ungleichmässiger Auftrag,  Unmöglichkeit des     Aufbringens    bei komplizierten  Teilen und dergleichen.  



  Ein neuartiger Weg wird mit dem erfindungs  gemässen Verfahren beschritten. Dieses ist dadurch  gekennzeichnet, dass die Körper in     eine    Suspension,  welche die Metallverbindungen in     feiest    verteiltem  Zustand enthält, eingetaucht und die Metallverbin  dungen durch Ultraschallbehandlung aus der Suspen  sion abgeschieden und auf die Körperoberflächen  aufgebracht werden. Insbesondere werden solche  Suspensionen verwendet, die     Wolfram-    und     Molyb-          dändisulfid    in Ölen oder     öl-Wasser-Emulsionen    ent  halten.  



  Es wurde gefunden, dass es     mit        Hilfe    der Schall  impulse einer     Ultraschallschwingung        gelingt,    die in  der Flüssigkeit in Schwebe befindlichen Metall  verbindungen in     gleichmässiger        Verteilung    und in  inniger Anlagerung auf feste Körper     aufzubringen.     Die Anlagerung an feste Körper wird durch die be  kannte Erscheinung begünstigt, dass die Ultraschall-    wellen zugleich eine     gründliche    Reinigung der Kör  peroberflächen     bewirken.     



       Ultraschall        wird    in der Technik für     mannigfache     Zwecke angewendet,     insbesondere    auch zur Herstel  lung beständiger Emulsionen, ferner zu     Reinigungs-          zwecken,    zur Entgasung von     Metallschmelzen,    für  die     zerstörungsfreie        Werkstoffprüfung    und dergleichen.  



  Durch die     Erfindung    ist für den     Ültraschall        ein     weiteres technisches Anwendungsgebiet erschlossen  und zugleich eine Lösung des Problems des Auf  bringens von Metallverbindungen aus Flüssigkeiten  auf feste Körper gefunden worden, die gegenüber  den bislang gebräuchlichen Methoden erhebliche  Vorteile bietet. Das erfindungsgemässe     Verfahren    ist  besonders geeignet zum     Aufbringen    von dünnen  selbstschmierenden Schichten, z. B. aus     Wolfram-          oder        Molybdändisulfid.  



      Method for applying metal compounds to solid bodies In order to store metal compounds on solid bodies, the procedure so far has been that they are either chemically, electrolytically or mechanically, z. B. by rolling, embossing or in some other way, applies under pressure. These methods have disadvantages such as uneven application, impossibility of application in the case of complicated parts and the like.



  A novel approach is taken with the process according to the invention. This is characterized in that the bodies are immersed in a suspension which contains the metal compounds in a finely distributed state and the metal compounds are separated from the suspension by ultrasound treatment and applied to the body surfaces. In particular, those suspensions are used that contain tungsten and molybdenum disulfide in oils or oil-water emulsions.



  It has been found that with the aid of the sound impulses of an ultrasonic oscillation it is possible to apply the metal compounds in suspension in the liquid to solid bodies in an even distribution and intimate attachment. The deposition on solid bodies is favored by the well-known phenomenon that the ultrasonic waves also cause thorough cleaning of the body surfaces.



       Ultrasound is used in technology for a variety of purposes, in particular for the production of stable emulsions, also for cleaning purposes, for degassing metal melts, for non-destructive testing of materials and the like.



  The invention opens up a further technical field of application for ultrasound and, at the same time, a solution to the problem of bringing metal compounds from liquids to solid bodies has been found, which offers considerable advantages over the methods previously used. The inventive method is particularly suitable for applying thin self-lubricating layers, such. B. made of tungsten or molybdenum disulfide.
