Mit einem Hartmetallpulver überzogene MetallplatteMetal plate coated with a hard metal powder

ist bekannt, Hartmetallpulver (Wolframkarbide und Sintermetalle) insbesondere durch Metallspritzgeräte auf vorher entsprechend gereinigte Metalloberflächen aufzubringen. Um eine besonder^" homogene Verbindung des Hartmetallpulvers mit dem Grundmaterial durch Aufschmelzen zu erzielen, ist es üblich, das mit dem Hartmetallpulver überzogene Werkstück zu erwärmen. Dies geschieht im allgemeinen durch Brenner verschiedener Form, auch unter Anwendung von Schutzgas oder in einem Ofen bei Temperaturen bis zu 12000O.It is known to apply hard metal powder (tungsten carbides and sintered metals), in particular by means of metal spraying devices, to previously appropriately cleaned metal surfaces. In order to achieve a particularly homogeneous connection of the hard metal powder with the base material by melting, it is customary to heat the workpiece coated with the hard metal powder. This is generally done using burners of various shapes, also using protective gas or in an oven at temperatures up to 1200 0 O.

Als nachteilig macht es sich dabei bemerkbar, daß bei der der Nacherwärmung folgenden Abkühlung Risse im Hartmetallüberzug und sogar in dem überzogenen Werkstück entstehen. Die Hisse treten im Werkstück besonders dann auf, wenn dieses eine hohe Chromlegierung aufweist.It is noticeable here as a disadvantage that cracks in the hard metal coating during the cooling following the reheating and even arise in the coated workpiece. The hoisting occurs in the workpiece especially when if it has a high chromium alloy.

Gemäß der Neuerung wird eine Metallplatte vorgeschlagen, die zwischen der gereinigten Oberfläche und dem Hartmetallüberzug eine Zwischenschicht aus im wesentlichen Rein-Nickel aufweist. Das Aufbringen erfolgt im allgemeinen durch Metallspritzen, doch können auch andere Verfahren zum Aufbringen der Zwischenschicht angewandt werden. Vorteilhafterweise beträgt die Schichtstärke etwa 0,05 - 0,1 mm. Wie praktischeAccording to the innovation, a metal plate is proposed between the cleaned surface and the hard metal coating an intermediate layer of essentially pure nickel having. The application is generally carried out by metal spraying, but other methods of application can also be used the intermediate layer can be applied. The layer thickness is advantageously approximately 0.05-0.1 mm. How practical

Versuche ergeben haben, tritt durch das Aufbringen der neuerungsgemäßen Zwischenschicht in fast allen Fällen nach dem Aufschmelzen des Hartmetallpulvers beim Abkühlen keine Rißbildung im Überzug und im Werkstück, auch bei stark chromlegiertem Werkstück, auf.Experiments have shown occurs through the application of the innovation Interlayer in almost all cases no cracking after the hard metal powder has melted on cooling in the coating and in the workpiece, even with heavily chromium-alloyed workpiece.

In der Zeichnung ist ein Ausführungsbeispiel der Neuerung dargestellt.In the drawing, an embodiment of the innovation is shown.

Die Figuren 1 und 2 zeigen eine ebene Metallplatte 4, die zwischen der metallisch reinen Oberfläche und dem Hartmetallüberzug 6 eine Zwischenschicht 5 aus im wesentlichen Rein-Uickel aufweist. Die Metallplatte 4 kann in beliebiger Form gebogen oder geformt sein. Es ist ferner möglich, derartige Platten zu Behältern, z.B. durch Schweißen, zu vereinigen oder bei der Herstellung von entsprechenden Werkstücken zu verwenden. Beide Überzugsschichten sind in ihrer Schichtstärke größer als in Wirklichkeit dargestellt.Figures 1 and 2 show a flat metal plate 4, which is between the metallically pure surface and the hard metal coating 6 has an intermediate layer 5 made of essentially pure nickel. The metal plate 4 can be in any Shape bent or shaped. It is also possible to combine such plates to form containers, for example by welding or to use in the production of corresponding workpieces. Both coating layers are in theirs Layer thickness greater than shown in reality.
