Abstract

Many workpieces have to be produced from high-grade materials, as there are often small areas which are subject to particular stress. A method is to be specified for workpieces, where the workpieces undergo a heating process and in which, selectively, only the highly stressed areas of the workpiece are treated. Before undergoing the heating process, sheets or plates are arranged adjacent to the places on the workpiece which are to be subjected to a surface treatment, the plates or sheets being adapted to the shape of the surface, containing alloy elements intended for the surface treatment and diffusing these into the workpiece during the subsequent heating process. Local surface treatment of high-grade workpieces.

Description

Die Erfindung betrifft ein Verfahren zur lokalen Oberflä­ chenbehandlung nach dem Oberbegriff des ersten Anspruchs.The invention relates to a method for local surface Chen treatment according to the preamble of the first claim.

Viele Werkstücke müssen aus hochwertigen Materialien her­ gestellt werden, weil an oftmals kleinen Flächen eine be­ sondere Beanspruchung vorliegt. Dadurch sind diese Werk­ stücke aufwendig und in der Herstellung mit großen Kosten verbunden.Many workpieces have to be made from high-quality materials be placed because in often small areas a be there is special stress. This makes these works elaborate and in the production at great cost connected.

Aufgabe der Erfindung ist es, ein Verfahren zur Oberflä­ chenbehandlung insbesondere zur Herstellung von hochwerti­ gen Werkstücken, die einen Heißprozeß durchlaufen, anzuge­ ben, bei dem gezielt nur die hoch beanspruchten Flächen behandelt werden.The object of the invention is a method for surface Chen treatment especially for the production of high quality against workpieces that go through a hot process ben, where only the highly stressed areas be treated.

Erfindungsgemäß wird dies dadurch gelöst, daß vor dem Durchlaufen des Heißprozesses den Stellen des Werkstückes, die eine Oberflächenbehandlung erfahren sollen, der Form der Oberfläche angepaßte Bleche oder Platten benachbart angeordnet werden, welche die zur Oberflächenbehandlung vorgesehenen Legierungselemente enthalten und diese beim anschließenden Heißprozeß in das Werkstück eindiffundie­ ren. According to the invention this is achieved in that before Going through the hot process the places of the workpiece, which are to receive a surface treatment, the shape matching sheets or plates adjacent to the surface are arranged, which are used for surface treatment contain intended alloying elements and these at subsequent diffusion process into the workpiece ren.  

Mit diesem Verfahren, welches vorteilhafterweise beim Gießen, Schmieden, Heißpressen und Härten angewendet wer­ den kann, werden in kostengünstiger Weise nur die Stellen des Werkstückes behandelt, welche einer besonderen Bean­ spruchung ausgesetzt sind.With this method, which is advantageous in Casting, forging, hot pressing and hardening are used only those positions can be cost-effectively of the workpiece, which is a special bean exposed to stress.

Beim Gießen ist es zweckmäßig, die Bleche oder Platten, welche die zur Oberflächenbehandlung vorgeseheen Legie­ rungselemente enthalten, mit Abschrecksteinen zu hinterle­ gen, wobei die Abschrecksteine eine steuerbare Temperatur aufweisen. Dies läßt sich vorteilhaft dadurch erreichen, daß die Abschrecksteine von einem Kühlmedium durchflossen sind. Erfindungsgemäß läßt sich das Aufschmelzen der Bleche oder Platten und die Abgabe der Legierungselemente an das Werkstück durch die Abschrecksteine steuern.When casting, it is advisable to which is the alloy intended for surface treatment contain elements with quenching stones gene, the quenching stones a controllable temperature exhibit. This can advantageously be achieved by that the quenching stones flow through a cooling medium are. According to the melting of Sheets or plates and the release of the alloying elements steer to the workpiece through the quenching stones.

In erfindungsgemäßer Ausführungsform kann der Heißvorgang, wie beschrieben, ein Gießvorgang, Schmiedevorgang, Härte­ vorgang oder ein Heißpressen sein.In the embodiment according to the invention, the heating process, as described, a casting process, forging process, hardness process or a hot press.

Ist der Heißvorgang ein Schmiedevorgang, so weist die Schmiedeform vorteilhafterweise Ausnehmungen zur Aufnahme der die Legierungselemente enthaltenen Bleche oder Platten auf.If the hot process is a forging process, the Forging shape advantageously recesses for receiving of the sheets or plates containing the alloy elements on.

Handelt es sich beim Heißvorgang um einen Härtevorgang, so liegen die Bleche oder Platten sinnvollerweise an der Oberfläche des Werkstückes fest an.If the hot process is a hardening process, so the sheets or plates are usefully on the Surface of the workpiece.

Wenn der Heißvorgang ein Heißpressen, insbesondere ein heißisostatisches Pressen ist, so liegen die Bleche oder Platten vorteilhafterweise gasdicht an der Oberfläche des Werkstückes an.If the hot process is a hot press, especially one hot isostatic pressing, the sheets or Plates advantageously gas-tight on the surface of the Workpiece.
