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.
