Description

Verfahren zur Erzielung einer festen Verbindung zwischen zwei mittels des Metallspritzverfahrens erzeugten Schichten verschiedener Metalle Die Erfindung betrifft ein Verfahren zur Erzielung einer festen Verbindung zwischen zwei Schichten verschiedener Spritzmetalle. Die unterste Schicht kann dabei auf einer beliebigen Unterlage unter Anwendung geeigneter Verankerungsmittel aufgebracht sein.Method for achieving a firm connection between two means The invention relates to a method for achieving a firm connection between two layers various spray metals. The bottom layer can be on any Underlay must be applied using suitable anchoring means.

Es ist für viele Anwendungszwecke nötig, Schichten aus verschiedenen Spritzmetallen möglichst fest miteinander zu verbinden. Dies geschieht zweckmäßig dadurch, daß man auf die rauhgespritzte Berste Schicht die zweite möglichst heiß und unter möglichst großem Druck aufspritzt.For many purposes it is necessary to have layers of different To connect spray metals as firmly as possible. This is done appropriately by placing the second as hot as possible on the rough-sprayed bursting layer and sprayed on under the greatest possible pressure.

Die Verbindung zwischen zwei solchen Spritzschichten hat sich häufig als mangelhaft hexausgestellt, wofür verschiedene Ursachen vorhanden sein können. Beispielsweise passen die beiden Spritzschichten nicht zusammen, oder die obere Spritzschicht verbindet sich nicht genügend mit der unteren Spritzschicht infolge ungenügenden Luftdrucks oder zu großer Härte der unteren Spritzschicht.The connection between two such sprayed layers has become common exhibited as inadequate hex, for which there may be various causes. For example, the two spray layers do not match, or the upper one Spray layer does not bond sufficiently with the lower spray layer as a result Insufficient air pressure or excessive hardness of the lower spray layer.

Diese mangelhafte Verbindung zwischen zwei solchen Spritzmetallschichten ist besonders dann nachteilig, wenn der mit den Schichten versehene Bauteil oder Körper und damit auch die Spritzmetallschichten größeren mechanischen Beanspruchungen unterworfen werden sollen.This poor connection between two such spray metal layers is particularly disadvantageous if the component provided with the layers or Body and thus also the spray metal layers are subject to greater mechanical stress should be subjected.

Die Erfindung beseitigt die Nachteile der bekannten Verfahren dadurch, daß auf das erste Spritzmetall eine Schicht aufgespritzt wird, die aus ;einer Mischung des ersten und des zweiten Spritzmetalls besteht. Brei einer bevorzugten Ausführungsform dieses Verfahrens wird die Mischung des ersten und zweiten Spritzmetalls dadurch erzeugt, daß gleichzeitig auf die gleiche Stelle das !erste Metall aus einer Spritzpistole und das zweite Metall aus einer zweiten Spritzpistole gespritzt werden.The invention eliminates the disadvantages of the known methods in that that a layer is sprayed onto the first spray metal which consists of a mixture of the first and second spray metal. Slurry of a preferred embodiment this process will result in the mixture of the first and second spray metal produced that at the same time the first metal from a spray gun on the same place and spraying the second metal from a second spray gun.

Auf diese Weise wird zwischen den beiden Spritzmetallschichten eine -Bindeschicht erzielt, die sich sowohl mit der inneren Schicht als auch mit der äußeren Schicht gut verbindet. Auf diese Weise wird Herreicht, daß die beiden aufgespritzten Metallschichten so fest aneinanderhaften, daß sie auch den größten mechanischen oder durch Witterungseinflüsse hervorgerufenen Beanspruchungen genügen.In this way there is one between the two spray metal layers -Bond layer, which interacts with both the inner layer and the outer layer connects well. In this way it is sufficient that the two sprayed on Metal layers adhere to one another so tightly that they even hold up the largest mechanical or stresses caused by the effects of the weather.
