Description

Die Erfindung betrifft ein Verfahren zur galvanischen Herstellung verschleißfester Metallüberzüge mit Schmiermitteleigenschaften, insbesondere von auf Schlag beanspruchten Metallteilen, wie Kipphebel od. dgl. aus Stahl, unter Verwendung von Trockenschmiermitteln, wie Graphit oder Metallsulfide.The invention relates to a method for the galvanic production of wear-resistant metal coatings with lubricant properties, especially of metal parts subject to impact, such as rocker arms od. Like. Made of steel, using dry lubricants such as graphite or metal sulfides.

Es ist bekannt, aus einer wäßrigen oder nicht wäßrigen Lösung Graphit auf der Oberfläche von Metallen elektrophoretisch abzuscheiden, um diese gegen Korrosion zu schützen oder gut gleitfähig zu machen. Ein so erzeugter Graphitüberzug ist jedoch nicht sehr verschleißfest und würde bei auf Schlag beanspruchten Maschinenteilen mehr oder weniger schnell zerstört.It is known from an aqueous or non-aqueous solution of graphite on the surface of Electrophoretically deposit metals in order to protect them against corrosion or to allow them to slide well do. A graphite coating produced in this way, however, is not very wear-resistant and would result in impact stressed machine parts destroyed more or less quickly.

Die Erfindung besteht demgegenüber darin, daß das Trockenschmiermittel einem galvanischen Bad zugesetzt und zusammen mit dem Metall abgeschieden wird. Auf Grund der Erfindung wird das Trockenschmiermittel in feinster Verteilung und sehr dauerhaft in der Oberfläche des Stahlteiles verankert, so daß es nur zusammen mit dem Metall von der Oberfläche des Kipphebels od. dgl. wieder entfernt werden könnte. Da das Metallsulfid oder sonstige Trockenschmiermittel aber den Antrieb der Oberfläche gerade zu unterbinden vermag, wird die Lebensdauer der erfindungsgemäß behandelten Teile entsprechend erhöht.In contrast, the invention consists in adding the dry lubricant to an electroplating bath and is deposited together with the metal. Based on the invention, the dry lubricant anchored in the finest distribution and very permanently in the surface of the steel part, see above that it is only removed together with the metal from the surface of the rocker arm or the like could. Since the metal sulfide or other dry lubricants drive the surface straight able to prevent, the life of the parts treated according to the invention is accordingly elevated.

Bei einer bevorzugten Ausführungsweise des Verfahrens wird als Trockenschmiermittel Zinksulfid und als galvanisches Bad ein Chrombad verwendet. Das Zinksulfid ist in der als Elektrolyt dienenden Lösung suspendiert. An Stelle einer Chromverbindung kann der Elektrolyt auch die Verbindung eines anderen Metalls enthalten. Die Trockenschmiermittelsuspension wird während der galvanischen Metallabscheidung umgerührt. Durch Elektrophorese wird die Mitabscheidung des Trockenschmiermittels begünstigt.In a preferred embodiment of the method, zinc sulfide and is used as the dry lubricant a chrome bath is used as a galvanic bath. The zinc sulfide is in the solution that serves as the electrolyte suspended. Instead of a chromium compound, the electrolyte can also be a compound of another Metal included. The dry lubricant suspension is used during the electrodeposition process stirred. The co-deposition of the dry lubricant is promoted by electrophoresis.
