Description

Werkstoff für die auf einen aus Leichtmetall gegossenen oder gepreßten Scheibenkörper aufzuspritzende verschleißfeste Brems- oder Lauffläche Zusatz zum Patent 825032 Im Patent 825 032 ist eine aus Leichtmetall hergestellte Brems- oder Kupplungsscheibe beschrieben, bei der auf den gegossenen oder gepreßten Scheibenkörper eine verschleißfeste Bremsfläche im Spritzverfahren aufgetragen ist. Material for the wear-resistant braking or running surface to be sprayed onto a cast or pressed disc body from light metal Addition to patent 825 032 Patent 825 032 describes a brake or clutch disc made from light metal, in which a wear-resistant braking surface is applied to the cast or pressed disc body by spraying is.

Als Ausgangsmaterial für die auf diese Weise erzeugte Bremsfläche wurde bisher Stahldraht verwendet, der einer Autogenflamme fortlaufend zugeführt wurde. Das durch die Flamme verflüssigte Material wird dabei von dieser gegen den sich drehenden Leichtmetallkörper geschleudert.As the starting material for the braking surface created in this way previously steel wire was used, which is continuously fed to an oxy-fuel flame became. The material liquefied by the flame is thereby against the rotating light metal body.

Gemäß der Erfindung läßt sich die Verschleißfestigkeit der Bremsfläche noch weiter erhöhen, wenn man pulverförmiges Gußeisen, insbesondere perlitisches Guß.eisen, auf die Brems- oder Lauffläche aufspritzt. Ein solches Pulver kann etwa einen Gehalt von 3,1 '/o C, r,20/a Si, 0,80/a Mn, o,6 °/a P, 0,o6 °/a S haben, wobei aber verschiedene Variationsmöglichkeiten hinsichtlich des Gehaltes an den Hauptbestandteilen möglich sind. Auf jeden Fall ist es zweckmäßig, dem Pulver eine solche Zusammensetzung zu geben, daß das Gefüge der auf die Brems- oder Kupplungsscheibe aufgespritzten Schicht dem eines perlitischen Gußeisens entspricht.According to the invention, the wear resistance of the braking surface Increase it even further if you use powdered cast iron, especially pearlitic Cast iron, sprayed onto the braking or running surface. Such a powder can be about have a content of 3.1 '/ o C, r, 20 / a Si, 0.80 / a Mn, 0.6 ° / a P, 0.06 ° / a S, where but different possibilities of variation with regard to the content of the main components possible are. In any case, it is advisable to add such a composition to the powder to give that the structure of the sprayed onto the brake or clutch disc Layer corresponds to that of a pearlitic cast iron.

Das Pulver wird auch hier, wie beim Gegenstand des Patents 825 032 der flüssige Stahl, durch eine Autogenflamme gegen die Bremsscheibe geschleudert. Durch nachträgliche Bearbeitung können Unebenheiten der aufgespritzten Schicht beseitigt bzw. die Schicht geglättet werden.Here too, as in the subject of patent 825 032 liquid steel, the powder is thrown against the brake disc by an oxy-fuel flame. Subsequent processing can remove unevenness in the sprayed-on layer or smooth the layer.
