Abstract
Description
Die Pulverzusammensetzung kann über die Schicht variieren, wenn eine Schicht mit örtlicher sich verändernden Eigenschaften gefordert wird. Bei verschleißfesten Schichten geschieht dieses durch Verändern des Hartstoffanteiles im Pulvermaterial. The powder composition can vary across the layer, if one Layer with locally changing properties is required. With wear-resistant Layers do this by changing the proportion of hard material in the powder material.
In der Zeichnung sind in den Fig. 1 und 2 je ein Ausführungsbeispiel der Erfindung im Querschnitt bzw in Draufsicht gezeigt. In the drawing are in Figs. 1 and 2 each an embodiment of the invention shown in cross section or in plan view.
Auf ein auf etwa 4000C vorgewärmtes Substrat 10 gemäß F i g. 1, wird ein Laserstrahl 11 mit einer Leistung von 5 kW und einer Geschwindigkeit von 6 mm/sec. On a preheated to about 4000C substrate 10 according to FIG. 1, will a laser beam 11 with a power of 5 kW and a speed of 6 mm / sec.
entlang einer vorgegebenen Linie (senkrecht zum Zeichnungsblatt der Fig. 1) geführt. Gleichzeitig wird über 12 eine Pulvermenge von 30 gimin auf die vom Laserstrahl 11 erzeugte Schmelzstelle 13 des Substrates 10 aufgebracht. Unter der Wirkung der Laserstrahlenenergie schmilzt das zugeführte Pulver, das sich dann mit der Schmelze 13 des Substrates eine Schichtspur 14 in der Form eines Streifens bildend verbindet. Unter den genannten Bedingungen erreicht man eine Schichtdicke d=2 mm und eine Breite b einer Schichtspur von etwa 8 mm.along a given line (perpendicular to the drawing sheet of the Fig. 1) out. At the same time, a powder amount of 30 gimin is applied to the 12 The melting point 13 of the substrate 10 generated by the laser beam 11 is applied. Under The action of the laser beam energy melts the powder that is fed in, which then spreads out with the melt 13 of the substrate, a layer track 14 in the form of a strip forming connects. A layer thickness is achieved under the conditions mentioned d = 2 mm and a width b of a layer track of about 8 mm.
In F i g. 1 sind verschiedene nebeneinander angeordnete Schichtspuren bzw. -streifen 14 im Querschnitt gestrichelt dargestellt, wobei die gestrichelte Form sich nur bei Abwesenheit von Nachbarspuren ergeben würde. Durch die Überlappung bildet sich insgesamt eine Schicht mit einer nahezu ebenen Oberfläche 17. In Fig. 1 are different layer tracks arranged next to one another or strips 14 shown in cross-section in dashed lines, with the dashed line Form would only result in the absence of neighboring tracks. Because of the overlap Overall, a layer with an almost flat surface 17 is formed.
Eine solche Schicht kann beispielsweise wie folgt hergestellt werden. Such a layer can be produced, for example, as follows.
Auf dem Übergangsbereich zwischen Lauffläche und Spurkranz von Eisenbahnrädern 20, Fig. 2, wird der Laserstrahl schraubenlinienförmig geführt, indem beispielsweise der Radkörper 23 um seine Achse mit einer für den Beschichtungsvorgang entsprechenden Geschwindigkeit gedreht und der Laserstrahl axial dazu verschoben wird. Der Laserstrahl 11 wird dabei um ca. On the transition area between the tread and the flange of railway wheels 20, Fig. 2, the laser beam is guided helically, for example the wheel body 23 about its axis with a corresponding for the coating process Speed rotated and the laser beam is shifted axially. The laser beam 11 is increased by approx.
5 mm automatisch versetzt, wenn es die erste Schichtspur erreicht. Die nächste Schichtspur 14 überlappt sich dabei mit der vorhergehenden Spur auf einer Breite Ü=3 mm. Der Überlappungsanteil 15 der neuen Schichtspur 14 wird dabei auf die vorhergehenden Schichtstreifen 14 unter gleichzeitiger Anhebung der Randschicht 26 des neuen Schichtstreifens 14 verlagert, so daß kein Talbereich entsteht.5 mm automatically offset when it reaches the first layer track. The next layer track 14 overlaps with the previous track a width Ü = 3 mm. The overlap portion 15 of the new layer track 14 is thereby onto the preceding layer strips 14 while at the same time raising the edge layer 26 of the new layer strip 14 shifted so that no valley area is created.
Der Radkörper wird zuvor an der Übergangsstelle 21 spanend vorprofiliert derart, daß die Oberfläche 22 der Beschichtung 26 nach deren Herstellung die erwünschte Formgebung hat. The wheel body is previously pre-profiled by cutting at the transition point 21 such that the surface 22 of the coating 26 after its production the desired Shape has.
Um einen kontinuierlichen Übergang von der Lauffläche 25 über die Schicht 26 zum Spurkranz 27 zu erhalten, wird während des Beschichtungsprozesses die Pulvermenge entsprechend verändert, das heißt ausgehend von einem Randbereich der Schicht 26 zunächst erhöht und dann wieder vermindert. To ensure a continuous transition from the tread 25 over the Layer 26 for flange 27 is obtained during the coating process the amount of powder changed accordingly, that is, starting from an edge area the layer 26 first increased and then decreased again.
Die so erhaltene Schicht hat eine fest ebene Oberfläche, die nur einer sehr geringen Nachbehandlung bedarf. Die Schicht ist eine sehr dichte und kompakte Schicht. The layer obtained in this way has a firm, flat surface that is only requires very little post-treatment. The layer is very dense and compact layer.
Bei der Verwendung von hochfesten und zähen Materialien wie Co- oder Ni-Matrix mit Hartstoffteilchen aus Wolframcarbid wird eine sehr dichte, harte und außerdem zähe Schicht erreicht, die dem Metallrad, wie dem Eisenbahnrad einen hohen Verschleißwiderstand verleiht und damit dem Gegenstand trotz hoher Beanspruchung eine relativ hohe Lebensdauer ermöglicht. When using high-strength and tough materials such as Co- or Ni matrix with hard material particles made of tungsten carbide is a very dense, hard and in addition, it reaches a tough layer, which gives a high level of metal and railway wheels Gives wear resistance and thus the object despite high stress allows a relatively long service life.
